Motion Retargeting Technique for Object Simulation and Animation

This application claims the benefit of U.S. Provisional Application No. 63/748,902 (Attorney Docket No. 24-TR-1177) entitled “Directable Motion Retargeting through Motion Paraphrasing,” filed Jan. 23, 2025, the entire contents of which is incorporated herein by reference.

At least one embodiment pertains to computer-based animation or modeling using neural networks. For example, at least one embodiment pertains to using neural networks to generate animations or models using a neural network and directed motion retargeting.

Motion retargeting involves methods for adapting existing motion data to a new character type. While motion retargeting finds many applications in fields such as animation, these methods may suffer from various deficiencies including lack of realism and lack of control. Accordingly, techniques for motion retargeting can be improved.

In the following description, numerous specific details are set forth to provide a more thorough understanding of at least one embodiment. However, it will be apparent to one skilled in the art that the inventive concepts may be practiced without one or more of these specific details.

In embodiments of the present disclosure, neural networks are used to perform motion retargeting. Motion retargeting may involve generating video or other motion-oriented data that represents a target character that is adapted from (e.g., mimics) the movements of a source character. Users of motion retargeting may, for example, be generating animated video or animated modelling data. Such users may wish to exercise additional control over the target character's movements, such as ensuring that the target character's movements are limited to a particular speed, ensuring that the range of motion exhibited by the characters' joints are realistic, and so forth.

Approaches to exercising this control could include tuning the neural network to generate results that conform to the desired constraints. However, these approaches may have various drawbacks, such as requiring additional tuning or being inflexible regarding which constraints can be applied to the output character's motion. In at least one embodiment, these drawbacks are addressed by using a diffusion neural network trained, using a motion paraphrasing dataset, to denoise paraphrased samples of motion data. Here, the notion of paraphrasing involves grouping potential motions into semantically similar groups having a plausible distribution of variations. The trained diffusion neural network then generates retargeted motion by inserting user-indicated constraints into noisy data that is denoised by the neural network to generate the output video or modeling data.

In at least one embodiment, the diffusion model generates frames of video by iteratively removing noise from a set of input data. In some one embodiments, the diffusion model generates retargeted motion sequences (e.g., per-frame joint positions and rotations) by iteratively removing noise from a set of input data, which can be subsequently rendered into video. In these embodiments, the input data corresponds to the parameters of a skeletal model that represents the character being animated. The parameters are initialized to random values, which can include noise. During the diffusion process, some of the noisy values are replaced with ground-truth representations derived from the user's constraints. This integration of user constraints help guide the diffusion process so that it generates output motion that is consistent with the constraints provided by the user. For example, if a user has specified that a character should exhibit relatively little arm swinging, the software might, at various points in the diffusion process, replace parameters of the skeletal model that represent the character's arms so that the degree of rotation in the arm joints is relatively close to zero, instead of random. This causes the resulting frame of video to be more likely to depict the character's arms in a neutral position, in accordance with the user's constraints.

This animation data may have applications in games, movies, simulation, augmented reality, virtual reality, and so forth. The directed motion retargeting modulemay perform motion retargeting that accommodates diverse human or other character morphologies, in order to create animation data that is more realistic and/or more useful for diverse types of simulations and applications. The directed motion retargeting modulemay generate such data using motion retargeting. Motion retargeting may refer to a process of transferring motions from one character to another, so that a type of motion exhibited by one character is reflected, in the generated data, in the other character. The directed motion retargeting modulemay be capable of motion retargeting even when the characters are of different morphologies. Embodiments of computing systemmay also be used in applications of motion synthesis models.

In at least one embodiment, computing systemas depicted includes one or more CPU(s), one or more GPU(s), and one or more memories. The memoriesmay comprise memory devices accessible to the CPU(s)and/or the GPU(s). The memoriesmay store instructions that, when executed by the CPU(s)and/or GPU(s), cause the computing device to perform operations and functions attributed to the directed motion retargeting module. In at least one embodiment, computing systemmay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

104 The directed motion retargeting modulemay comprise software and/or hardware to perform operations and functions attributed to it herein, including operations and functions associated with performing training and/or inference associated with directed motion retargeting and/or directed motion paraphrasing.

In at least one embodiment, motion retargeting preserves the salient characteristics of the source motion while generating natural movements appropriate for the target character. However, the nature of this problem may be ambiguous, because the best solution in any one instance can depend on what the user considers to be the essential characteristics of the source motion, and how they want these characteristics adapted to the target character's morphology and behavior. Some approaches to this problem, such as optimization-based methods, may attempt to resolve this ambiguity by providing precise user control in the form of constraints, such as joint position and rotation constraints. However, while this approach provides users with flexibility, it is challenging to maintain motion quality, as the optimization lacks priors for human motion. As a result, achieving realistic results using this approach could require extensive manual intervention, such as specifying dense keyframes or meticulous tuning of constraints. Other methods may use neural retargeting models to learn how to adapt motions to different morphologies by leveraging large motion datasets. By training on motions performed by characters with different morphologies, these methods can generate plausible retargeted motions automatically, requiring minimal manual user intervention. However, these learned methods lack the controllability needed for users to explore different retargeting possibilities to best suit their needs.

102 126 104 126 302 304 3 FIG. In at least one embodiment, the computing systemoutputs retargeted motiongenerated by directed motion retargeting module. The retargeted motioncomprises depictions of natural motions for a target character morphology, preserving the core semantics of a source motion while also allowing users to direct results according to their needs. This may be done using motion paraphrasing. The technique of motion paraphrasing may be described as analogous to text paraphrasing, which takes the core idea of a sentence and expresses it in different vocabularies or sentence structures. Similarly, motion paraphrasing may comprise taking a unit of source motion and reenacting the core aspects of that unit of motion with a different target character, where these core aspects correspond to the underlying semantic meaning of the source motion. While the core aspects are adhered to, the approach still allows expressive variations that users can direct. For example, motion paraphrasing of the box stepping motion in the source motiondepicted byshould maintain, in the retargeted motions, the stepping height of the character due to the semantic content and constraints associated with the movement, while the arm movements may vary.

104 In at least one embodiment, directed motion retargeting moduleemploys directed motion paraphrasing (DMP), a motion retargeting framework based on motion paraphrasing, which offers a range of possible retargeting solutions, intuitive control over the output motions, and realistic retargeted motions that align with the morphology of a given target character.

In at least one embodiment, the directed motion retargeting modulecomprises one or more neural networks implementing a directed motion retargeting architecture, such as the directed motion retargeting architecturedepicted in, which is based on diffusion neural models. These neural networks may be trained using a motion paraphrasing dataset. The motion paraphrasing datasetmay consist of motion capture recordings from diverse subjects performing similar motion sequences. The computing systemthen trains the neural networks to generate plausible variations of a given source motion on different target skeletons. For finer-grained control over the retargeted motions, the computing system, at inference time, enables users to specify flexible kinematic constraints to be applied to the retargeted motiongenerated by the system. These user constraints may be incorporated into the neural network architecture through a combination of masked in-painting and loss guidance.

In some instances, constraintsare not provided for an initial generation of retargeted motion, but are provided subsequently during a process of iterative refinement. The source motionmay comprise video, skeletal model and corresponding motion data, or other similar information. The target charactermay comprise video, a skeletal model, or other similar information. Where video is provided, it may be converted by computing systeminto a skeletal model format, or any other format suitable for processing by the directed motion retargeting module. The constraintsmay comprise information indicating restrictions on joint positions, permissible degrees of rotation, permissible distances between body parts or other surfaces, or collision avoidance information. It will be appreciated that these examples are intended to be illustrative rather than limiting. The directed motion retargeting module, as explained further herein, generates a retargeted motionbased on the source motion, target character, and constraints.

In this example embodiment, the circuitry of the processor(s) generates noise representations that include representations of character attributes conforming to the constraints, and use the one or more neural networks to generate the frames of video. The example embodiment does so by denoising the noise representations. Examples of noise representations and techniques for generating noise representations are disclosed herein, including for example with respect to. The constraints on the character attributes may, in some aspects of this example embodiment, pertain to position, direction, angle, rotation, velocity, and/or contacts. Position, direction, angle, rotation, and velocity may pertain to the movement of the character itself, whereas contacts may include contact between that character and other characters or objects.

120 122 In some aspects of this example embodiment, the indicated motions are indicated by motions of another character. For example, the indication motions may be indicated by a character depicted in the source motion, and applied to the target character.

6 FIG. In some aspects of this example embodiment, attributes conforming to the constraints and are included in noise representations as in-painted ground truth data. This inpainting may be intermittently applied, for example by in-painting attributes conforming to the one or more constraints in only a subset of noise representations used to generate the frames of video. Examples of in-painting are described herein, including for example with respect to.

In at least one embodiment, a system implements a directed motion retargeting modulethat preserves semantically relevant characteristics of a source motion, while also offering users control and refinement over the resulting motions using constraints. The directed motion retargeting modulemay correspond to the directed motion retargeting moduledescribed in conjunction with. The source motion, target skeleton, and constraintsmay correspond to the source motion, target character, and constraintsdepicted in. In at least one embodiment, examplemay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

1 FIG. As described in relation to, embodiments may employ directed motion paraphrasing to perform the retargeting. The use of motion paraphrasing may maintain high-level semantics while accommodating natural variations in low-level details. Motion paraphrasing may be understood in view of text paraphrasing, where multiple sentence variations, such as changes in wording, length, etc., can convey the same underlying meaning. Similar to how a writer can adjust individual words and sentence structure while paraphrasing until they are satisfied with the details, the user of a directed motion retargeting system, as disclosed herein, may allow users to control retargeting within a distribution of plausible variations.

202 204 206 212 212 208 206 210 206 The example depicts an example embodiment of a workflow for performing directed motion retargeting. Given a source motion, a target skeleton, and optional constraintssuch as joint positions, rotations, distance between body parts, and geometric collision avoidance, the directed motion retargeting modulegenerates diverse yet plausible motion retargeting solutions, preserving high-level semantics close to those of the source motion. Users can then select one or more solutions from the results or further refine them by modifying existing constraints or specifying additional constraints. For example, the directed motion retargeting modulemight initially generate outputwithout constraints (i.e., before constraintsare specified), and then generate outputswith constraints at the user's request, after constraintsare specified. With the new or updated constraints, the system uses the motion paraphrasing model to re-generate retargeting solutions that adhere to the new or revised constraints while preserving or further enhancing motion naturalness and semantics. Through this iterative process, users can start with a broad range of unconstrained motions and progressively refine them to achieve their desired outcome.

3 FIG. 3 FIG. 1 FIG. 10 29 FIGS.- 300 302 304 302 304 300 illustrates examplesof source motionsand retargeted motionsusing directed motion paraphrasing, in accordance with at least one embodiment. As depicted in, source motionsmay have certain features that are semantically related to a motion being retargeted. For example, in the upper example, the position of the character's hands may be semantically related to the character's arm-raising gesture. Other features, such as the character's leg positions, may not be semantically important to the same gesture. Accordingly, in the retargeted motions, the character's leg positions may vary from the original while the hand positions are planned and controlled, by a directed motion retargeting module such as the one depicted in, to track more closely to hand positions in the source movement. In at least one embodiment, examplemay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

302 304 Similarly, in the lower example, the position of the character's legs in source motionsmay be expected to vary, in the retargeted motions, based on differences in the source and target character's morphologies. The starting and ending positions of the character's feet, on the other hand, may be considered semantically important to the paraphrased movement.

5 FIG. In at least one embodiment, one or more neural networks of a motion retargeting module are trained by obtaining or generating a motion dataset comprising various individuals performing the same actions. These neural networks may include aspects of a diffusion architecture, as described in more detail in relation to. The neural networks may be trained to identify the distribution of retargeting variations from the motion paraphrasing dataset. After training, users can specify additional constraints to apply to the generation. These may then be incorporated into the neural network's diffusion process through masked in-painting and loss guidance.

In at least one embodiment, to capture a wide variety of possible motion retargeting solutions for training the neural networks, a large-scale motion paraphrasing dataset is constructed to comprise motion capture recordings from diverse subjects performing similar behaviors. For example, the dataset could be constructed by instructing motion capture actors to mimic or enact a particular behavior given visual or text prompts, and having each actor perform the behavior multiple times to exhibit natural variations in the motion. The recorded motions of the actors can then be grouped according to the respective prompts, producing a dataset containing groups of motion clips from different actors that correspond to the same underlying behaviors. Random pairs of motion clips can then be sampled from each group to produce examples of how actors with different body shapes perform a similar behavior. Note, however, that these motion pairs may often be temporally misaligned since each actor may have different motor capabilities and movement styles. The motion clips may also have different speeds and include varying lengths of idle motions at the beginning or end of the clip, leading to additional misalignments. These misalignments may cause undesirable effects within the retargeting workflow. In at least one embodiment, misalignment is addressed by temporally filtering and aligning the motion pairs through subsequence dynamic time warping (DTW).

4 FIG. 402 404 406 illustrates an example of aligning motion pairing data using dynamic time warping, in accordance with at least one embodiment. At a high level, this approach comprises application of an algorithm that finds an optimal or approximately optimal match, after re-timing, between the frames of two sequencesand/or. This may be based on a user-defined similarity metric. In at least one embodiment, a similarity cost is heuristically defined between the i-th pose

A 402 408 of motion M, corresponding to a first sequence, and the j-th pose

B 404 of a second motion M, corresponding to a second sequenceby

R ω h c d where R denotes the joints rotations, w represents the angular velocities, h refers to the average foot heights, f are the binary foot contact labels, and d denotes the 2D root displacement on the ground plane. The operator ⊕ measures the geodesic distance between two rotations. Weights w=1, w=2, w=5, w=0.3, w=0.5 may be used to balance the terms. If the best-alignment cost across the trajectory is higher than a specified threshold after DTW, this means a good match cannot be found and the motion pair may be discarded.

In at least one embodiment, motion clips are segmented into short subsequences, to which subsequence DTW is then applied. This may be done because large discrepancies between actors may be more prevalent when capturing longer motion sequences, making good matches more difficult to find. In at least one embodiment, given two motions from the same behavior group, one motion is randomly segmented into a short subsequence, and an optimal subsequence within the other motion that best matches the short segment of the first motion is determined through subsequence DTW.

root 3 2 (j×6) (j−1)×3 (j×3) 4 root 1 In at least one embodiment, to capture diversity of retargeting variations, a diffusion-based motion paraphrasing model is used. To incorporate directability into the model, random masked in-painting is applied during training to help the model learn to respect motion constraints specified at inference time. A motion M is represented as a sequence of frame features, and a feature at frame i consists of the root position p∈, root heading direction θ=(cos θ, sin θ)∈R, where is the planar rotation angle, joint rotations {1, . . . ,}∈Rencoded in a 6D representation, joint positions {2, . . . ,}∈R, joint velocities {1, . . . ,}∈R, and foot contact labels∈{0, 1}, where denotes the number of joints, with the superscriptreserved for the root. The root position and heading direction may be expressed relative to the planar root coordinate system at the first frame of the motion. The origin of this coordinate system corresponds to the root position projected onto the ground, while the rotation may be determined by the heading direction, the world up-vector, and their normalized cross-product. Joint positions may be expressed with respect to the planar root coordinate frame, excluding the planar root position since it remains constant within this coordinate frame. Foot contact labels may be Boolean values that indicate whether feet and toes are in contact with the ground or objects, computed by whether the joint velocity is below a threshold.

In at least one embodiment, a generative diffusion model is used for motion paraphrasing to capture complex distributions from large datasets while allowing motion retargeting to be controllable through in-painting and test-time guidance. In at least one embodiment, the generative diffusion model is trained following a Denoising Diffusion Probabilistic Models (DDPM) framework. In some embodiments, the generative diffusion model is trained using one or more forward passes, and gradually perturbs a data sample with Gaussian noise across diffusion steps t, and one or more backward passes to denoise the perturbed data sampled back towards a clean sample. The model may additionally be trained using the DDPM framework further, to perform motion retargeting, conditioning the model on one or more source motions, source skeletons, and/or target skeletons, thereby allowing the denoiser to model the distribution of plausible redirected target motions while respecting user constraints via masked in-painting and guidance.

θ 0 t t-1 j−1 520 510 In some embodiments, given a motion from the data distribution 0~( ), a forward diffusion process can progressively apply Gaussian noise at each diffusion step to transform the data distribution ( ) to an isotropic Gaussian distribution N (0, I) as →∞. The denoising process may be defined as the reverse process, which iteratively denoises starting from noise~N(0, I) and progresses to the data distribution 0~( ). Since the true conditional distribution of the reverse process is unknown, a denoiser may be trained to approximate it as (−1|,) where is a set of learnable parameters and denotes a set of additional context information provided as input to the denoiser. The denoiser πpredicts the clean motion {circumflex over (M)}=π(M, t, C) which may be noised back to {circumflex over (M)}in the sampling process. To generate a motion that aligns with a source motion and a given target skeleton, the denoiser network incorporates the source motion src, the source skeleton src, and the target skeleton tgt into the context. The skeleton's morphology∈Rmay be represented by the length of each link. In at least one embodiment, a multilayer perceptron (MLP)is included to refine diffusion step.

In at least one embodiment, to enable user directability of retargeted motions, the model is trained with randomly sampled constraints as input. The constraints may be created by randomly sampling a subset of motion features from the ground-truth target motion, such as root position, heading orientation, joint positions, and joint rotations. Constrained features may be indicated by a binary mask which has the same dimension as a motion. Then, feature constraints from the ground-truth target motion tgt 0 may be directly in-painted into the motion currently being denoised

~ where ⊙ refers to element-wise multiplication. The masked motiontgt may then be provided as input to the denoiser, along with the mask to indicate which features are constrained.

A design decision when randomly generating constraints during training is the structure of the constraint sampling process. One approach is naïve random sampling of which motion feature dimension(s) to constrain. However, this approach may lack the structure of typical user-specified constraints. For example, randomly sampling features of a 6D joint rotation representation may impose constraints on only one element, whereas users might be more likely to constrain the entire rotation in their actual workflow.

4 FIG. 10 29 FIGS.- In at least one embodiment, a structured constraint sampling scheme is implemented to better emulate likely user workflows. For each training example, several keyframes may be randomly selected. Then, constraint features may be sampled in groups at each keyframe, which may, for example, constrain all joint positions, all joint rotations, joint positions of certain body parts, joint rotations of certain body parts, the root trajectory, sparse root positions or heading orientations. In at least one embodiment, with a probability of 0.1 for each keyframe, no constraints are imposed, which enables the model to retarget plausible motion in both conditional and unconditional settings. In at least one embodiment, one or more techniques and/or methods associated withmay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with

In at least one embodiment, inputs to the transformer decoder are first processed by linear embeddings,and a positional encoder.

6 FIG. 6 FIG. 600 illustrates an example processfor performing directed motion retargeting, in accordance with at least one embodiment. Although the example process ofis depicted as including operations performed in series, it will be appreciated that embodiments of the depicted process can be implemented without necessarily adhering to the depicted order. For example, embodiments may perform steps in a different order or in parallel, except where explicitly indicated or logically required.

600 600 102 104 600 600 1 FIG. 10 29 FIGS.- The example processcan be performed to cause a directed motion retargeting model to generate a retargeted motion. For example, the example processmight be performed by the computing systemand/or the directed motion retargeting moduleof. The example processmay be performed during training and/or inference. Note that the use of a directed motion retargeting module to generate a retargeted motion may be described herein as being related to an inference stage of using a neural network, to distinguish between training phases of the neural networks and the post-training use of said module. However, it will be appreciated that the neural network also performs similar inference operations during training. In at least one embodiment, one or more techniques and/or methods of processmay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

602 604 At, the example process obtains source motion and user constraints and atinitializes a representation of noisy motion. For example, in at least one embodiment, at inference time, random noise is sampled from a standard Gaussian distribution.

606 608 610 612 614 src src tgt At, user constraints may be encoded as a mask m. In some embodiments, mask m may be encoded as a binary motion-feature mask indicating constrained features across frames. Then, at,, and, the noisy motion may be iteratively denoised given a source motion Mand skeleton S, target skeleton s, and a motion constraint mask m. To accelerate the generation process, Denoising Diffusion Implicit Models (DDIM) sampling may be employed. When no constraints are provided (i.e., m is all zeros), the model may generate a distribution of retargeted motions on the target skeleton that are semantically identical to the source, while exhibiting natural variations. The clean retargeted motion may then be output at.

In at least one embodiment, beyond exploring diverse retargeting variations, users can further direct the model by specifying spatio-temporal constraints, such as joint positions, rotations, inter-body-part distance, and collision avoidance. These constraints may be integrated into denoising using masked in-painting and/or loss guidance. The interleaving of in-painting and/or guidance with the denoising steps during sampling may help to preserve the naturalness of motion, which would otherwise be difficult to achieve with traditional optimization-based techniques.

In at least one embodiment, users can apply constraints to the retargeting process by directly specifying desired values for various motion features. Similar to training time, the constraint values may be directly in-painted into the current noisy motion

at each denoising timestep t of the reverse process before being given to the denoiser,

usr where Mis a feature vector that includes user-specified values.

In at least one embodiment, in addition to masked in-painting, diffusion guidance is used to enable more accurate enforcement of constraints. Guidance also supports more flexible constraints, such as constraint types that cannot be easily specified through in-painting. For example, these constraint types can include spatial relationship between body parts or objects, and collision avoidance. Let l(M) be an analytical loss function that quantifies the difference between the user-provided constraints and the constraints obtained from a (clean) retargeted motion M. To reduce constraint violation, a predicted motion

0 can be updated by the gradient of the objective function at each denoising step to produce a corrected motion {tilde over (M)},

where w is the step size for the update. Note, the gradient is computed with respect to the noisy input motion

0 0 t rather than the predicted clean motion {circumflex over (M)}. Compared to computing the gradient with respect to {circumflex over (M)}, which affects only the features directly used for computing the loss l, computing the gradient with respect to Mmay allow a sparse constraint to have dense influence on all frames and features by back-propagating gradient through the denoiser model, enabling a more coherent change to the overall motion. Guidance objectives are designed to constrain joint position, rotation, relative joint position, self-penetration avoidance, object collision avoidance, and object contact.

Examples of guidance objective functions that may be employed include global joint position, joint rotation, relative joint position, self-penetration avoidance, object collision avoidance, and object contact. Embodiments may also use guidance objectives other than these guidance objectives, and custom objective functions can be specified according to user requirements.

j j j 0 p The global positions of joints may convey important semantic information, especially for object and scene interaction behaviors. Let {circumflex over (R)}, {circumflex over (p)}=FK({circumflex over (M)}) be the global joint rotation and position of joint j, where FK denotes a forward-kinematics operation. To encourage the resulting motion to reach a target positionwith joint j, the guidance objective can be specified simply with the position error

R j Similarly, guidance objective for reaching a target joint rotationcan be specified by,

where ⊕ computes the geodesic distance between two rotations. This can be useful when it is desired to copy subtle high-frequency details from source to target motion.

The relative spatial relationship of two joints may also convey important semantic cues that may not be captured through independent joint positions alone. For example, in a drinking motion, a character's hand should move toward their mouth. To preserve such relative spatial relationship, the following objective may be used:

j j i,j represents the relative position of i-th joint with respect to j-th joint. {circumflex over (R)}and {circumflex over (p)}denote the global rotation and joint positions of the respective joints, computed using the same forward-kinematics described above. {circumflex over (p)}is the desired relative position, which can be computed from the source motion.

When the generated motions are applied to characters with meshes, self-penetration may occur, which can undermine the plausibility of the motion. Guidance can also be applied to prevent these self-penetration artifacts. To address this, a character's mesh can be approximated using spheres, and self-penetration can then be minimized by penalizing penetration depths among the spheres. The penetration depth between i-th sphere and j-th sphere can be computed by

i j i j where cand care the centers of sphere i and j, respectively, and rand rare their respective radii. The penetration depths of adjacent spheres that initially overlap in the T-pose, are excluded from the computation.

When a character is moving through a scene, it should usually avoid not only self-penetration but also unnecessary collisions with external objects. A character's occupancy mesh can be approximated using spheres. If the i-th sphere collides with k-th object, the collision may be penalized by

k i where SDFrepresents the signed distance field of the k-th object, and ris the radius of the i-th sphere.

In contrast to avoiding collisions with certain objects, there are also scenarios where contact with specific objects is necessary. For example, hands should touch a box in order to grab it. To encourage the generated motion to correctly contact an object, while also allowing for flexibility in determining the contact positions, a contact objective be defined by

i,k where cis a binary variable indicating whether the i-th sphere should make contact with the k-th object.

7 FIG. 7 FIG. 700 illustrates a further example process for performing directed motion retargeting, in accordance with at least one embodiment. Although the example processofis depicted as including operations performed in series, it will be appreciated that embodiments of the depicted process can be implemented without necessarily adhering to the depicted order. For example, embodiments may perform steps in a different order or in parallel, except where explicitly indicated or logically required.

700 102 104 1 FIG. In at least one embodiment, the example processis implemented by a system comprising a directed motion retargeting module, such as the computing systemand directed motion retargeting moduledepicted in.

702 508 504 5 FIG. At, the system obtains constraints and attributes of a character to be depicted, in generated motion data, as performing an indicated motion. The indicated motions, in at least one embodiment, correspond to motions of another character. For example, the indicated motions may correspond to the target skeletonand/or source motionof. The constraints can comprise, as non-limiting examples, any of the constraints described herein, including but not limited to joint position, direction, joint rotation, relative joint position, joint angle, rotation, velocity, self-penetration avoidance, object collision avoidance, and object contact. User-customized constraints can also be obtained, for example by receiving and incorporating custom objective functions as described above.

704 702 At, the system generates a noise representation comprising attributes that conform to the constraints obtained at. The noise representation can correspond, in at least one embodiment, to

506 5 FIG. the motion to denoisethat is depicted in relation to. For example, in at least one embodiment, the attributes conforming to the one or more constraints are included in the one or more noise representations as in-painted ground truth data. By using attributes conforming to the constraints in a subset of the noise representations used to generate motion data, the diffusion process is guided to generate data that conforms to the constraints. As noted above, not using constraints in at least some iterations during training enables the model to learn to retarget plausible motion in both conditional and unconditional settings. In at least one embodiment, the attributes to be included in a noise representation for a given iteration are selected using a randomized selection from a plurality of attributes that might be constrained.

706 600 500 708 700 6 FIG. 5 FIG. 10 29 FIGS.- At, the system iteratively denoises the noise representations. In at least one embodiment, this may be performed as described in relation to the processdepicted inand the exampleof a neural network architecture that is depicted in.

In at least one embodiment, one or more techniques and/or methods of processmay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

8 8 FIGS.A-C 1 FIG. 8 8 FIGS.A-C 1 FIG. 8 FIG.A 8 FIG.B 8 FIG.C 10 29 FIGS.- 102 104 800 810 820 800 810 820 illustrate an example user interface for inputting directed motion retargeting, in accordance with at least one embodiment. Animators or other users can utilize a directed motion retargeting system using a system such as the computing systemdepicted in. A user can, in at least one embodiment, interact with a user interface that provides a means for visualizing unconstrained retargeted motion and iteratively adding constraints of various types. For example, as depicted in, an interactive program can be provided. Given a source motion and a target skeleton, users can use the depicted user interface to visualize unconstrained motion samples generated by a diffusion-based paraphrasing model, such as the neural networks used in the directed motion retargeting moduleof. Then, using a graphical user interface, users can iteratively add constraints of various types, such as joint position constraints, and instruct the system to regenerate motions that conform to the indicated requirements. Finally, the user can select one or more retargeted motions for final use. In the exampleof, position constraints are applied by a user, using the user interface, to a character's hands to indicate that the character's hands should reach towards a target position. In the exampleof, object collision constraints are applied by a user, using the user interface, to indicate that the character should duck under an obstacle. In the exampleof, joint rotation constraints are applied by a user, using the user interface, to ensure limits to the range of motion of the indicated joints, while allowing the system to infer the motion of other joints accordingly. In at least one embodiment, one or more techniques and/or methods of process,, and/ormay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

9 FIG. 9 FIG. 10 29 FIGS.- 902 904 906 900 illustrates examples of constrained and unconstrained motion retargeting using directed motion paraphrasing, in accordance with at least one embodiment. The examples illustrate directed motion paraphrasing outputs guided by various types of user constraints applied through masked in-painting and loss guidance. Compared to undirected generation from the same model, applying constraints such as object avoidance, wrist joint positions, and arm rotations further enhances the physical plausibility and overall quality of the motion, while aligning more closely with user intent. These concepts are illustrated inby examples of source motionand examples of unconstrained retargeted motionand constrained retargeted motion. In at least one embodiment, one or more techniques and/or methods of processmay be implemented in conjunction with one or more of the components and/or systems described below in conjunction with.

9 FIG. Besides unconstrained retargeting, directed motion paraphrasing supports constrained (directed) retargeting, where the user can specify spatial-temporal constraints at inference time. The example depicted in the first row ofvisualizes a character turning back and running to the left. With added ceiling and object avoidance constraints, the character crouches more to run below the ceiling. The second example shows a character jumping off a wall. With enforced contact constraints added to the hand and foot joints, the character better preserves the contacts (green boxes) from the source motion. The last example depicts a character performing a hip-hop dance. With joint rotation constraints (red dots) specified on the arm joints at every frame, the character dances in a more similar rhythm and magnitude with the source motion.

4 FIG. In at least one embodiment, a motion paraphrasing dataset is constructed from a large motion capture dataset containing motion from approximately 100-200 participants. The participants include approximately equal numbers of male and female, with heights ranging from 145 cm to 199 cm, roughly following a normal distribution (mean 174.3 cm, std 10.9 cm). The dataset includes common motion categories such as locomotion, everyday activities and gestures, and combat with a variety of styles. The raw motion captures vary from 1 to 180 seconds in length. The dataset consists of thousands of distinct behaviors, each performed by multiple actors and for multiple repetitions. These distinct behaviors are split into a non-overlapping train (90%) and test set (10%), such that the test set will not contain any behaviors used during training. Motion pairs are constructed for training using the subsequence dynamic time warping process described in relation to, resulting in relatively short motion pairs ranging from 1 to 4 seconds in length. The final motion paraphrasing training set contains 67M motion pairs. To better handle object interactions at test time (e.g., walking up stairs with variable step heights or jumping on boxes with variable heights), the training dataset is augmented by randomly scaling both the source and target character skeletons by the same scaling factor, along with their corresponding root translations. The scale factor is uniformly sampled between 0.8 and 1.2.

30 40 In at least one embodiment, a motion paraphrasing data set is referred to as a BML-MP Dataset. A BML-MP dataset may include approximately 200 subjects performing similar motions across-categories, totaling approximately 12 hours of motion data. The participants include balanced numbers of females and males, with heights following a roughly normal distribution. The dataset includes everyday actions and sports movements: kick, point, clap, cross arms, run in place, crawl, walk, wave, check watch, side gallop, vertical jump, sit chair, sit ground, throw and catch, run, scratch head, phone call, jumping jack, take a photo, walk in a treadmill (four speed variations: fast, jog, normal, and slow), motorcycle, walk, jog, sit, lift objects (two variations: light and heavy object), throw hard, kick, jump, knock, and walk in circle. The datasets might also include freeform improvisation for each participant, but these are discarded as they are inappropriate for finding motion paraphrasing pairs. The raw motion captures vary from 1 to 133 seconds in length, with an average of 8 seconds. Selected motion categories and subjects may be excluded from the training set and used as test motions and test subjects, respectively. A resulting BML-MP may contain approximately two million motion paraphrasing pairs, each 1 to 4 seconds long. During training, random scaling of the character skeletons may be applied.

Neuromorphic computing devicecan include a neuromorphic processor from Intel Corporation in Santa Clara, CA or another processor that shares at least some of the components described herein. As shown in this example, a devicemay be provided with a networkof multiple neural network cores interconnected by an on-device network such that multiple different connections may be potentially defined between cores. For instance, a networkof spiking neural network cores may be provided in deviceand may each communicate via short packetized spike messages sent from core to core over network channels. Each core (e.g.,) may possess processing and memory resources and logic to implement some number of primitive nonlinear temporal computing elements, such as, but not limited to, multiple (e.g., 1000+) distinct artificial neurons (referred to herein as “neurons”). For instance, each core may be capable of concurrently implementing multiple neurons such that neuromorphic cores may implement many multiples of neurons using device.

16 FIG. 1605 1620 1625 1605 1630 1605 1610 1610 1605 1625 1630 1610 1610 Continuing with the example of, neuromorphic computing devicemay additionally include processorand system memoryto implement one or more components to manage and provide functionality of neuromorphic computing device. For instance, system managermay be provided to manage global attributes and operations of neuromorphic computing device(e.g., attributes affecting network of cores, multiple cores in network, interconnections of neuromorphic computing devicewith other devices, manage access to global system memory, among other potential examples). In one example, system managermay manage the definition and provisioning of a specific routing tables to various routers in network, orchestration of a network definition and attributes (e.g., weights, decay rates, etc.) to be applied in network, core synchronization and time multiplexing management, routing of inputs to appropriate cores, among other potential functions.

1605 1635 1610 1605 1610 1635 1615 1615 As another example, neuromorphic computing devicemay additionally include programming interfacethrough which a user or system may specify a neural network definition to be applied (e.g., through a routing table and individual neuron properties) and implemented by meshof neuromorphic cores. A software-based programming tool may be provided with or separate from neuromorphic computing devicethrough which a user may provide a definition for a particular neural network to be implemented using networkof neuromorphic cores. Programming interfacemay take an input of a programmer to then generate corresponding routing tables and populate local memory of individual neuromorphic cores (e.g.,) with specified parameters to implement a corresponding, customized network of artificial neurons implemented by neuromorphic cores.

1605 1640 1640 1640 1605 In some cases, neuromorphic computing devicemay advantageously interface with and interoperate with other devices, including general purpose computing devices, to realize certain applications and use cases. Accordingly, external interface logicmay be provided in some cases to communicate (e.g., over one or more defined communication protocols) with one or more other devices. An external interfacemay be utilized to accept input data from another device or external memory controller acting as a source of input data. External interfacemay be additionally or alternatively utilized to allow results or output of computations of a neural network implemented using neuromorphic computing deviceto be provided to another device (e.g., another general purpose processor implementing a machine learning algorithm) to realize additional applications and enhancements, among other examples.

16 FIG. 16 FIG. 1610 1615 1615 1650 1615 1650 1610 1615 1650 1650 1605 1605 1610 1605 a d a d a d a d As shown in, networkof multiple neural network cores interconnected by an on-device network is shown illustrating a portion of a network fabric interconnecting multiple neuromorphic cores (e.g.,-). For instance, a number of neuromorphic cores (e.g.,-) may be provided in a mesh, with each core being interconnected by a network including a number of routers (e.g.,). In one implementation, each neuromorphic core (e.g.,-) may be connected to a single one of routers (e.g.,) and routers may be connected to at least one other router (as shown atin). As an example, in one particular implementation, four neuromorphic cores (e.g.,-) may be connected to a single router (e.g.,) and each of routersmay be connected to two or more other routers to form a manycore mesh, allowing each neuromorphic core to interconnect with each other neuromorphic core in neuromorphic computing device. Moreover, as each neuromorphic core may be configured to implement multiple distinct neurons, router network of neuromorphic computing devicemay similarly enable connections, or artificial synapses (or, simply, “synapses”), to be defined between any two of potentially many (e.g., 30,000+) neurons defined using network of neuromorphic coresprovided in neuromorphic computing device.

16 FIG. 1615 1615 1615 1655 1615 1615 1615 1615 1665 1670 1610 1615 1670 1615 1615 1605 1615 shows a block diagram illustrating internal components of one example implementation of neuromorphic core. In one example, a single neuromorphic core may implement some number of neurons (e.g. 1024) that share architectural resources of neuromorphic corein a time-multiplexed manner. In one example, each neuromorphic coremay include processor blockcapable of performing arithmetic functions and routing in connection with the realization of a digitally implemented artificial neuron, such as, but not limited to, explained herein. Each neuromorphic coremay additionally provide local memory in which a routing table may be stored and accessed for a neural network, accumulated potential of each soma of each neuron implemented using coremay be tracked, parameters of each neuron implemented by coremay be recorded, among other data and usage. Components, or architectural resources, of neuromorphic coremay further include input interfaceto accept input spike messages generated by other neurons on other neuromorphic cores and output interfaceto send spike messages to other neuromorphic cores over mesh network. In some instances, routing logic for neuromorphic coremay be at least partially implemented using output interface. Further, in some cases, core (e.g.,) may implement multiple neurons within an example SNN and some of these neurons may be interconnected. In such instances, spike messages sent between neurons hosted on coremay forego communication over routing fabric of neuromorphic computing deviceand may instead by managed locally at particular neuromorphic core.

1675 1680 1685 1680 1610 1685 1680 1680 1610 1685 1660 1675 1675 1670 Each neuromorphic core may additionally include logic to implement, for each neuron, artificial dendriteand artificial soma(referred to herein, simply, as “dendrite” and “soma” respectively). Dendritemay be a hardware-implemented process that receives spikes from network. Somamay be a hardware-implemented process that receives each dendrite's accumulated neurotransmitter amounts for the current time and evolves each dendrite and soma's potential state to generate outgoing spike messages at the appropriate times. Dendritemay be defined for each connection receiving inputs from another source (e.g., another neuron). In one implementation, dendrite processmay receive and handle spike messages as they serially arrive in time-multiplexed fashion from network. As spikes are received, neuron's activation (tracked using soma(and local memory)) may increase. When neuron's activation exceeds a threshold set for neuron, neuronmay generate a spike message that is propagated to a fixed set of fanout neurons via output interface. Network distributes spike messages to all destination neurons, and in response those neurons, in turn, may update their activations in a transient, time-dependent manner, and so on, potentially causing the activation of some of these destination neurons to also surpass corresponding thresholds and trigger further spike messages, as in real biological neural networks.

1605 1605 1605 1610 16 FIG. As noted above, neuromorphic computing devicemay reliably implement a spike-based model of neural computation. Such models may also be referred to as Spiking Neural Networks (SNNs). In addition to neuronal and synaptic state, SNNs also incorporate the concept of time. For instance, in an SNN, communication occurs over event-driven action potentials, or spikes, that convey no explicit information other than the spike time as well as an implicit source and destination neuron pair corresponding to the transmission of the spike. Computation occurs in each neuron as a result of the dynamic, nonlinear integration of weighted spike input. In some implementations, recurrence and dynamic feedback may be incorporated within an SNN computational model. Further, a variety of network connectivity models may be adopted to model various real world networks or relationships, including fully connected (all-to-all) networks, feed-forward trees, fully random projections, “small world” networks, among other examples. A homogeneous, two-dimensional network of neuromorphic cores, such as, but not limited to, shown in the example ofmay advantageously supports all of these network models. As some or all cores of neuromorphic computing devicemay be connected, some or all neurons defined in cores may be therefore also fully connected through some number of router hops. Neuromorphic computing devicemay further include fully configurable routing tables to define a variety of different neural networks by allowing each core's neurons to distribute their spikes to any number of cores in meshto realize fully arbitrary connectivity graphs.

16 FIG. In an improved implementation of a system capable of supporting SNNs, such as, but not limited to, a very large scale integration (VLSI) hardware device illustrated in the example of, high speed and reliable circuits may be provided to implement SNNs to model information processing algorithms as employed by a brain, but in a more programmable manner. For instance, while a biological brain can only implement a specific set of defined behaviors, as conditioned by years of development, a neuromorphic processor device may provide a capability to rapidly reprogram all neural parameters. Accordingly, a single neuromorphic processor may be utilized to realize a broader range of behaviors than those provided by a single slice of biological brain tissue. This distinction may be realized by adopting a neuromorphic processor with neuromorphic design realizations that differ markedly from those of neural circuits found in nature.

1605 1605 2 As an example, a neuromorphic processor may utilize time-multiplexed computation in both a spike communication network and neuron machinery of neuromorphic computing deviceto implement SNNs. Accordingly, physical circuitry of neuromorphic computing devicemay be shared among many neurons to realize higher neuron density. With time multiplexing, a network can connect N cores with O(N) total wiring length, whereas discrete point-to-point wiring would scale as O(N), realizing a significant reduction in wiring resources to accommodate planar and non-plastic VLSI wiring technologies, among other examples. In neuromorphic cores, time multiplexing may be implemented through dense memory allocation, for instance, using Static Random Access Memory (SRAM), with shared buses, address decoding logic, and other multiplexed logic elements. State of each neuron may be stored in processor's memory, with data describing each neuron state including state of each neuron's collective synapses, all currents and voltages over its membrane, among other example information (such as, but not limited to, configuration and other information).

A neuromorphic processor may adopt a “digital” implementation that diverts from other processors adopting more “analog” or “isomorphic” neuromorphic approaches. For instance, a digital implementation may implement integration of synaptic current using digital adder and multiplier circuits, as opposed to analog isomorphic neuromorphic approaches that accumulate charge on capacitors in an electrically analogous manner to how neurons accumulate synaptic charge on their lipid membranes. Accumulated synaptic charge may be stored, for instance, for each neuron in local memory of a corresponding core. Further, at an architectural level of an example digital neuromorphic processor, reliable and deterministic operation may be realized by synchronizing time across a network of cores such that any two executions of a design, given same initial conditions and configuration, will produce identical results. Asynchrony may be preserved at a circuit level to allow individual cores to operate as fast and freely as possible, while maintaining determinism at a system level. Accordingly, a notion of time as a temporal variable may be abstracted away in neural computations, separating it from a “wall clock” time that the hardware utilized to perform the computation. Accordingly, in some implementation, a time synchronization mechanism may be provided that globally synchronizes neuromorphic cores at discrete time intervals. A synchronization mechanism allows neural computation to complete as fast as circuitry allows, with a divergence between run time and biological time that a neuromorphic system models.

1605 In operation, neuromorphic computing devicemay begin in an idle state with all neuromorphic cores inactive. As each core asynchronously cycles through its neurons, it generates spike messages that a mesh interconnect routes to appropriate destination cores containing all destination neurons. Implementation of multiple neurons on a single neuromorphic core may be time-multiplexed, and a time step may be defined in which all spikes involving multiple neurons may be processed and considered using shared resources of a corresponding core. As each core finishes servicing its neurons for a respective time step, cores may, in some implementations, communicate (e.g., using a handshake) with neighboring cores using synchronization messages to flush a mesh of all spike messages in flight, allowing cores to safely determine that all spikes have been serviced for a time step. At that point all cores may be considered synchronized, allowing them to advance their time step and return to an initial state and begin a next time step.

1605 1610 1615 1615 1680 1610 1685 Given this context, and as introduced above, a device (e.g.,) implementing a meshof interconnected neuromorphic cores may be provided, with coreimplementing potentially multiple artificial neurons capable of being interconnected to implement an SNN. Each neuromorphic core (e.g.,) may provide two loosely coupled asynchronous processes: an input dendrite process (e.g.,) that receives spikes from networkand applies them to an appropriate destination dendrite compartments at the appropriate future times, and output soma process (e.g.,) that receives each dendrite compartment's accumulated neurotransmitter amounts for the current time and evolves each dendrite and soma's membrane potential state, generating outgoing spike messages at appropriate times (e.g., when a threshold potential of a soma has been reached). Note that, from a biological perspective, dendrite and soma names used here only approximate a role of these functions and should not be interpreted too literally.

23 FIG.A 23 FIG.A 23 FIG.A 23 FIG.A 2304 2306 2308 2312 2310 2314 2316 2300 2302 2300 2300 2300 2300 illustrates a diagram of an example many-core tiled processor microarchitecture. Many-core tiled processor incan include a language processing processor. As illustrated in, each “tile” of a processor architecture is a processing element tied together using a network-on-chip (NoC) that can be used, e.g., to perform some or all of the operations described above or elsewhere herein. For example, each tile may have an instruction dispatchand an integer (INT)and floating-point (FP) unitas well as load-store unit (LSU)to interface with memory hierarchy (data cache (D$)and instruction cache (I$)) and network (NET)interface for communication with other tiles. Some tiles in processormay include memory controllerfor managing and controlling memory, as described further herein. Processorcan have a functional slice architecture. Processormay be located on an application specific integrated circuit (ASIC), andmay represent a layout of an ASIC. Processorcan include a co-processor that is designed to execute instructions for a predictive model. A predictive model is any model that is configured to make a prediction from input data. A predictive model can use a classifier to make a classification prediction. A predictive model may be a machine learning model such as, but not limited to, a tensor flow model, and processoris a tensor streaming processor.

2300 2324 2300 2304 2318 2320 2322 2300 2304 2300 23 FIG.B 23 FIG.B Processorcan employ different microarchitectures, which disaggregates functional units shown in each tile in. Instead, functional tilesof processormay be aggregated into a plurality of functional process units (hereafter referred to as “slices”), each corresponding to a particular function type (e.g., FP/INT, NET, MEM). For example, as illustrated in, each slice may correspond to a column of functional tiles extending in a north-south direction. In addition, processoralso may include communication lanes to carry data between tiles of different slices, each running horizontally in an east-west direction. Each communication lane may be connected to each of slicesof processor.

2304 2300 2318 2320 2322 2304 2300 Slicesof processormay each correspond to a different function, and may include arithmetic logic slices (e.g., FP/INT), lane switching slices (e.g., NET), and memory slices (e.g., MEM). Arithmetic logic units may execute one or more arithmetic and/or logic operations on data received via communication lanes to generate output data. Examples of arithmetic logic units may be matrix multiplication units and vector multiplication units. Memory slices include memory cells that store data. Memory slices can provide data to other slices through communication lanes. Memory slices can also receive data from other slices through communication lanes. Lane switching slices can configurably route data from one communication lane to any other communication lane. For example, data from a first lane can be provided to a second lane through a lane switching slice. In some embodiments, a lane switching slice can be implemented as a crossbar switch. Each slicealso includes its own instruction queue (not shown) that stores instructions, and an instruction control unit (ICU) to control execution of instructions. Instructions in a given instruction queue may be executed only by tiles in its associated functional slice and may not be executed by other slice(s) of processor.

2300 2304 2300 2300 2300 23 FIG.B 23 FIG.B By arranging tiles of processorinto different functional slices, on-chip instruction and control flow of processorcan be decoupled from data flow. For example, one arrow inillustrates flow of instructions within processor architecture, in accordance with some embodiments. Another arrow inillustrates data flow within processor architecture, in accordance with at least one embodiment. As illustrated, instructions and control flow can flow in a first direction across tiles of processor(e.g., north-south, along a length of functional slices, as shown by the first arrow), while data flows flow in a second direction across tiles of processor(e.g., east-west, across functional slices, as shown by the second arrow) that is perpendicular to the first direction.

2300 2322 2300 2300 Different functional slices of processormay correspond to MEM(memory), VXM (vector execution module), MXM (matrix execution module), NIM (numerical interpretation module), and SXM (switching and permutation module). Each slice may include N tiles that may all be controlled by a same instruction control unit (ICU) (not shown). Each slice may operate completely independently and can only be coordinated using barrier-like synchronization primitives or through a compiler by exploiting “tractable determinism.” Each tile of processorcan correspond to an execution unit organized as an ×M SIMD tile. For example, each tile of on-chip memory of processormay be organized to store an L-element vector atomically. As such, a MEM slice having N tiles may work together to store or process a large vector (e.g., having a total of N×M elements).

Tiles in a slice may execute instructions in a “staggered” fashion where instructions may be issued tile-by-tile within a slice over a period of N cycles. Functional slices may be arranged physically on-chip to allow efficient dataflow for pipelined execution across hundreds of cycles for common patterns. Data flows can perform a single “u-turn” (change in direction) corresponding to a single matrix operation before being written back to memory, in some embodiments, a particular data flow may change direction multiple times (due to multiple matrix and vector operations) before resulting data is written back into memory.

2300 2300 2300 When using processor(e.g., TSP) having a functional slice architecture, TSP compiler (not shown) generates an explicit plan for how processorcan execute a program (e.g., a microprogram). Compiler can specify when each operation will be executed, which functional slices will perform work, and which STREAM registers hold operands. Compiler can maintain a high-fidelity (cycle accurate) model of processor(e.g., TSP) hardware state so a microprogram can orchestrate data flow.

2300 2300 Processor(e.g., TSP) can use a Web-hosted compiler that takes as its input a model (e.g., a ML model such as, but not limited to, a TensorFlow model) and emits a proprietary instruction stream targeting processor(e.g., TSP). Compiler is responsible for coordinating control and data flow of a program, and specifies any instruction-level parallelism by explicitly bundling instructions that can and should execute concurrently so that they may be dispatched together. Primary hardware structure includes an architecturally-visible streaming register file (STREAMs), described in greater detail below, which serves as a conduit through which operands flow from MEM slices (e.g., SRAM) to functional slices and vice versa.

2322 2300 2300 2300 2300 2300 MEMof processorcan serve as: (1) storage for model parameters, microprograms and data on which they operate, and (2) network-on-chip (NoC) for communicating data operands from MEM to functional slices and computed results back to MEM. In some embodiments, on-chip memory can consume ≈75% of chip area of processor. In some embodiments, due to bandwidth requirements of processor, on-chip memory of MEM tiles may include SRAM, and not DRAM. On-chip memory capacity of processorcan determine (i) number of ML models that can simultaneously reside on-chip, (ii) size of any given model, and (iii) partitioning of large models to fit into multi-chip systems. In some embodiments, MEM system of processorcan provide a plurality of memory slices organized into two different hemispheres (referred to as “MEM WEST” and “MEM EAST”, respectively).

2300 Memory slices of each hemisphere may be mirrored, such that slices may be physically numbered {0, . . . . L} in an East hemisphere, and {L, . . . 0} in a West hemisphere, such that memory slice 0 for each hemisphere corresponds to a slice closest to VXM slices between hemispheres, where each hemisphere comprises L slices. Direction of data transfer towards the center of a chip may be referred to as inwards, while data transfer toward the outer (Eastern or Western most) edge of a chip may be referred to as outwards. Although hemispheres of memory of processormay be referred to as east and west, it is understood that in other embodiments, other names may be used to refer to different hemispheres of memory.

2300 In some embodiments, a streaming register file, referred to as STREAMS, transfers operands and results between SRAM of MEM slices and functional slices of processor. In some embodiments, a plurality of MEM slices (e.g., between 2 and 10 adjacent MEM slices) may be physically organized as a set. Each set of slices may be located between a pair of STREAM register files, such that each slice is able to read or write to STREAM registers in either direction. By placing STREAM register files between sets of MEM slices, a number of cycles needed for data operands to be transmitted across a hemisphere is decreased (e.g., by a factor corresponding to a number of slices per set).

2400 2403 2405 2407 2408 2403 2403 2403 2403 2403 2402 2403 Software stackof a programming platform can include a number of libraries, a runtime, an optional driver/interface, and a device kernel driver. Each of librariesmay include data and programming code that can be used by computer programs and leveraged during software development. Librariesmay include pre-written code and subroutines, classes, values, type specifications, configuration data, documentation, help data, and/or message templates. Librariescan include functions that may be optimized for execution on one or more types of devices. Librariesmay include functions for performing mathematical, deep learning, and/or other types of operations on devices. Librariescan be associated with corresponding APIs, which may include one or more APIs, that expose functions implemented in libraries. A processor (e.g. CPU, GPU) may perform, call, or otherwise use one or more APIs to prioritize kernels. For example, a first kernel (e.g., parent) can launch a second kernel (e.g., child kernel), and said second kernel can be used by a processor to launch additional kernels (e.g., grandchildren kernels) independent of said first kernel. A processor may perform an API or calls an API from memory to be performed to support dynamic stream priority (e.g., updating priority while a stream is being used to perform operations). For example, when a processor performs said API, it allows a programmer to copy stream priority from one stream to one or more other streams.

2400 2400 2400 2400 2400 Software stackmay include an API to support dynamic stream priority (e.g., updating priority while a stream is being used to perform operations), which can allow a programmer to set priority of a stream at any time after creation. Software stackcan include an API to support dynamic stream priority (e.g., updating priority while the stream is being used to perform operations), which may allow a programmer to obtain current priority of a stream, where the priority is one of a plurality of attributes of a stream. Software stackcan include an API to support dynamic stream priority (e.g., updating priority while the stream is being used to perform operations), which may allow a programmer to obtain current priority of a stream as a single attribute. Software stackcan include an API to support dynamic stream priority (e.g., updating priority while the stream is being used to perform operations), which allows a programmer to launch a kernel to perform operations on a stream at a set priority, which may be different from the stream priority. Software stackmay include an API to indicate whether an object (e.g., a thread synchronization object such as, but not limited to, a barrier) tracks whether all data movement operations for a set of threads operating on a GPU may be complete has a specified state after a specified period of time, where a specified state can be a state indicating that data has been moved and is ready for use, and is specified using an expected parity value as an input to the API.

2400 2400 2400 Software stackcan include one or more APIs to updated kernels. A processor can perform an API or call an API from memory to be performed to update to an existing API is to support context-free kernels, which may allow a programmer to add a kernel node to a graph without a graphics context, so that a graphics context can be dynamically associated with a kernel at runtime. Software stackmay include one or more APIs to allow a programmer to obtain a kernel identifier and a graphics context as separate parameters from a kernel node, so that parameters to be obtained from kernels and from context-free kernels. Software stackcan include one or more APIs to use parallel processor(s), such as, but not limited to, one or more graphics processing units, to launch task graphs (e.g., task graphs) and to execute one or more task graphs (e.g., including one or more programs).

2400 2400 Software stackmay include one or more APIs to associate one or more instructions with one or more memory ordering operations, such as, but not limited to, a fence or membar operation. Instructions can be associated with one or more domains such that a memory ordering operation is executed in association to one or more particular domains without interfering with instructions of other domains. An API can indicate a thread has arrived (e.g., at a thread synchronization barrier), or finished a stage of work in relation to asynchronous data movement operations on a GPU. Software stackmay include one or more to allow programmers to manually indicate an expected transaction count when a thread has finished a stage of work, which can be used to update an object that tracks whether all data movement operations for a set of threads may be complete.

2401 2401 2400 2401 2405 2405 2401 25 26 FIGS.and Applicationcan be written as source code that is compiled into executable code, as discussed in greater detail below in conjunction with. Executable code of applicationmay run, at least in part, on an execution environment provided by software stack. During execution of application, code may be reached that needs to run on a device, as opposed to a host. In such a case, runtimemay be called to load and launch requisite code on a device. Runtimemay include any technically feasible runtime system that is able to support execution of application.

2405 2404 Runtimecan be implemented as one or more runtime libraries associated with corresponding APIs, which are shown as API(s). One or more of such runtime libraries may include functions for memory management, execution control, device management, error handling, and/or synchronization, among other things. Memory management functions may include functions to allocate, deallocate, and copy device memory, as well as transfer data between host memory and device memory. Execution control functions may include functions to launch a function (sometimes referred to as a “kernel” when a function is a global function callable from a host) on a device and set attribute values in a buffer maintained by a runtime library for a given function to be executed on a device.

2404 Runtime libraries and corresponding API(s)may be implemented in any technically feasible manner. One (or any number of) API may expose a low-level set of functions for fine-grained control of a device, while another (or any number of) API may expose a higher-level set of such functions. A high-level runtime API may be built on top of a low-level API. One or more of runtime APIs may be language-specific APIs that may be layered on top of a language-independent runtime API.

2407 2407 An optional driver or interfacemay be implemented, e.g., for CUDA and ROCm implementations, that are described further below. Optional driver/interfacemay be associated with optional driver or interface API(s), such as, but not limited to, CUDA and/or ROCm API(s).

2400 1100 1200 1234 1300 1400 1500 1605 1700 1800 1900 2000 2100 2200 2300 2400 One or more processors disclosed in “processing systems” can perform, access, or otherwise use software stack. For example, system-on-a-chip, parallel processor, graphics multiprocessor, processor, processor, accelerator, neuromorphic processor, supercomputer, acceleration processing unit, processor, processor, tensor processing unit, processor, and language processing unitcan perform, use, call, or otherwise implement (e.g., through accessing a memory) one or more APIs included in software stack.

2408 2408 2404 2408 2408 2408 Device kernel drivercan be configured to facilitate communication with an underlying device. Device kernel drivermay provide low-level functionalities upon which APIs, such as, but not limited to, API(s), and/or other software relies. Device kernel drivermay be configured to compile intermediate representation (“IR”) code into binary code at runtime. For CUDA or other implementations such as, but not limited to, ROCm, OneAPI, or OpenCL, device kernel drivermay compile Parallel Thread Execution (“PTX”) IR code that is not hardware specific into binary code for a specific target device at runtime (with caching of compiled binary code), which is also sometimes referred to as “finalizing” code. Doing so may permit finalized code to run on a target device, which may not have existed when source code was originally compiled into PTX code. Alternatively, device source code may be compiled into binary code offline, without requiring device kernel driverto compile IR code at runtime.

Additionally, the one or more constraints on the one or more attributes of the character may comprise one or more of position, direction, angle, rotation, velocity, or contacts, and the one or more indicated motions are indicated by motions of another character. Furthermore, the one or more attributes conforming to the one or more constraints and are included in the one or more noise representations as in-painted ground truth data. In some embodiments, the systems, services, and/or circuitry is further configured to use the one or more attributes conforming to the one or more constraints in a subset of noise representations used to generate the frames of video, and is to include the representations of one or more attributes in the one or more noise representations based, at least in part, on random selection of the one or more attributes from a plurality of attributes.

Similar to a CUDA runtime APIimplemented by a CUDA runtime library (cudart), CUDA driver APImay expose functions for memory management, execution control, device management, error handling, synchronization, and/or graphics interoperability, among other things. CUDA driver APIcan differ from CUDA runtime APIin that CUDA runtime APIsimplifies device code management by providing implicit initialization, context (analogous to a process) management, and module (analogous to dynamically loaded libraries) management. In contrast to high-level CUDA runtime API, CUDA driver APIcan be a low-level API providing more fine-grained control of a device, particularly with respect to contexts and module loading. CUDA driver APImay expose functions for context management that may be not exposed by CUDA runtime API. CUDA driver APImay also be language-independent and support, e.g., OpenCL, in addition to CUDA runtime API. Further, development libraries, including CUDA runtime, may be considered as separate from driver components, including user-mode CUDA driverand kernel-mode device driver(also sometimes referred to as a “display” driver).

A compileris configured to receive source code, compile source code, and output an executable file. Compliercan be configured to convert source codeinto host executable codefor execution on a host and device executable codefor execution on a device. Source codemay either be compiled offline prior to execution of an application, or online during execution of an application. Source codemay include code in any programming language supported by compiler, such as, but not limited to, C++, C, Fortran, etc. Source codemay be included in a single-source file having a mixture of host code and device code, with locations of device code being indicated therein. A single-source file may be a.cu file that includes CUDA code or a.hip.cpp file that includes HIP code or a file in another format that includes both host code and device code. Alternatively, source codemay include multiple source code files, rather than a single-source file, into which host code and device code may be separated. Compilerincludes or has access to one or more libraries to recognize a sequence of API calls to perform a single fused API, where a single fused API is a combined API for two or more APIs. In at least one embodiment, compilermay be an NVIDIA CUDA compiler (“NVCC”) for compiling CUDA code in.cu files, or a HCC compiler for compiling HIP code in.hip.cpp files, or other compilers.

2501 2500 2507 2508 2501 2500 2500 2501 2508 2507 2508 2507 Compilercan be configured to compile source codeinto host executable codefor execution on a host and device executable codefor execution on a device. Compilerperforms operations including parsing source codeinto an abstract system tree (AST), performing optimizations, and generating executable code. When source codeincludes a single-source file, compilermay separate device code from host code in such a single-source file, compile device code and host code into device executable codeand host executable code, respectively, and link device executable codeand host executable codetogether in a single file.

2501 2502 2505 2506 2509 2502 2504 2503 2500 2504 2506 2508 2503 2505 2507 2505 2506 2505 2506 Compilercan include a compiler front end, a host compiler, a device compiler, and a linker. Compiler front endcan be configured to separate device codefrom host codein source code. Device codemay be compiled by device compilerinto device executable code, which as described may include binary code or IR code, in at least one embodiment. Separately, host codemay be compiled by host compilerinto host executable code. For NVCC other compilers, such as, but not limited to, those for oneAPI, ROCm, and OpenCL, host compilermay be a general purpose C/C++ compiler that outputs native object code, while device compilermay be a Low Level Virtual Machine (“LLVM”)-based compiler that forks a LLVM compiler infrastructure and outputs PTX code or binary code. For HCC, both host compilerand device compilermay be LLVM-based compilers that output target binary code.

2500 2507 2508 2509 2507 2508 2510 2507 2508 2507 2508 2507 2508 Subsequent to compiling source codeinto host executable codeand device executable code, linkercan link host and device executable codeandtogether in executable file. Native object code for a host and PTX or binary code for a device may be linked together in an Executable and Linkable Format (“ELF”) file, which is a container format used to store object code. Host executable codeand device executable codemay be in any suitable format, such as, but not limited to, binary code and/or IR code. In the case of CUDA, host executable codemay include native object code and device executable codemay include code in PTX intermediate representation, in at least one embodiment. In the case of ROCm, both host executable codeand device executable codemay include target binary code, in at least one embodiment. Other implementations, such as, but not limited to, oneAPI, OpenCL are contemplated and can be performed similarly to the CUDA and ROCm implementations above.

2500 2500 2501 2507 2508 2500 2501 2507 2508 25 FIG. Source codemay be translated prior to compiling source code. Source code is passed through a translation tool (not shown), which translates source codeinto translated source code. A compilercan be used to compile translated source code into host executable codeand device executable codein a process that is similar to compilation of source codeby compilerinto host executable codeand device executable code, as discussed above in conjunction with.

2500 2500 2500 2501 2500 26 FIG. A translation performed by translation tool can be used to port source codefor execution in a different environment than that in which it was originally intended to run. Translation tool may include a HIP translator that is used to “hipify” CUDA code intended for a CUDA platform into HIP code that can be compiled and executed on a ROCm platform. Translation of source codemay include parsing source codeand converting calls to API(s) provided by one programming model (e.g., CUDA) into corresponding calls to API(s) provided by another programming model (e.g., HIP), as discussed in greater detail below in conjunction with. Returning to the example of hipifying CUDA code, calls to CUDA runtime API, CUDA driver API, and/or CUDA libraries may be converted to corresponding HIP API calls. Automated translations performed by translation toolmay sometimes be incomplete, requiring additional, manual effort to fully port source code.

2501 2501 2501 2500 2501 2500 2510 2501 2505 2506 One or more techniques described herein may utilize a variety of methods for converting one type of code to another type of code. For example, compileror other compilers described herein can convert a high-level language (e.g., source code that is abstract to hardware) to a lower-level language (e.g., machine code or an intermediate representation). Source code can be scanned, parsed, transformed into an abstract syntax tree semantically analyzed, then converted into an intermediate code, and then converted into machine code or assembly language. Compileror other compilers described herein can include a transpiler, which can convert, for example, one type of source code to another type of source code or one type of machine code to another type of machine code. Source code can be parsed, and transformed into an abstract syntax tree, which can then be converted to an intermediate model that can be transformed into an abstract syntax tree of target language and code can be generated. Compileror other compilers described herein can be used to enable interchangeability between different device architectures. For example, an application for one platform (e.g., a CUDA application) can be compiled into code for implementation on another platform (e.g., an AMD processor, Intel processor, or other processor). Source codecan include source code for one platform (e.g., CUDA). Compilercan compile the sourceinto an executable filethat can be used by another platform (e.g., AMD or Intel). Programming toolkits can allow applications for one platform (e.g., CUDA) to be compiled (e.g., natively) for another platform (e.g., AMD or Intel). For example, a GPGPU programming toolkit can allow for CUDA applications to be natively compiled for AMD GPUs. Programs (e.g., CUDA programs) or its build system do not have to be modified or translated to another language before compiling to code for another platform. A compiler may accept the same command-line options and programming dialect (e.g., CUDA dialect) as another compiler (e.g., nvcc for CUDA), serving as a drop-in replacement to impersonate an installation of a toolkit (e.g., NVIDIA CUDA Toolkit), so existing build tools and scripts (e.g., like cmake) work without further modification. In at least one embodiment, an nvcc-compatible compiler can be used to compile nvcc-dialect CUDA for AMD GPUs, including PTX asm. Implementations of CUDA runtime and driver APIs for AMD GPUs can be used. Libraries (e.g., open source wrapper libraries) can provide APIs, such as “CUDA-X” APIs by delegating to the corresponding ROCm libraries. An example implementation includes SCALE from Spectral Compute in London, England. SCALE can allow programs written using CUDA language to be directly compiled to lower-level language (e.g., machine code) for AMD GPUs. SCALE can create one or more directories that can be used to impersonate NVIDIA CUDA Toolkit (from the point of view of a build system) by instructing a build system that a CUDA installation path is one provided by SCALE, rather than the one provided by NVIDIA. Additional implementations can include a Clang compiler that can provide a language front-end and tooling infrastructure for languages in the C language family (C, C++, Objective C/C++, OpenCL, CUDA, and RenderScript). In at least one embodiment, compilers and/or transpilers described herein, such as, but not limited to compiler, compiler, and/or compilercan include one or more circuits to compile code (e.g., CUDA, HIP, OpenCL, OneAPI, or others) to obtain one or more constraints on one or more attributes of a character to be depicted as performing one or more indicated motions in frames of video to be generated by one or more neural networks, generate one or more noise representations to comprise one or more representations of one or more attributes conforming to the one or more constraints, and use the one or more neural networks to generate the frames of video based, at least in part, on denoising of the one or more noise representations. Additionally, the one or more constraints on the one or more attributes of the character may comprise one or more of position, direction, angle, rotation, velocity, or contacts, and the one or more indicated motions are indicated by motions of another character. Furthermore, the one or more attributes conforming to the one or more constraints and are included in the one or more noise representations as in-painted ground truth data. In some embodiments, the systems, services, and/or circuitry is further configured to translate code to use the one or more attributes conforming to the one or more constraints in a subset of noise representations used to generate the frames of video, and is to include the representations of one or more attributes in the one or more noise representations based, at least in part, on random selection of the one or more attributes from a plurality of attributes. Further, the one or more neural networks are trained based, at least in part, on sets of video each comprising a plurality of character types performing the same type of motion, and/or perform any of the operations described above or elsewhere herein.

2501 2505 2506 In at least one embodiment, compilers and/or transpilers described herein, such as, but not limited to compiler, compiler, and/or compilercan include one or more circuits to convert code (e.g., source code for CUDA) to one or more other types of code (e.g., machine code for CUDA and/or another platform, such as AMD or Intel processors) to obtain one or more constraints on one or more attributes of a character to be depicted as performing one or more indicated motions in frames of video to be generated by one or more neural networks, generate one or more noise representations to comprise one or more representations of one or more attributes conforming to the one or more constraints, and use the one or more neural networks to generate the frames of video based, at least in part, on denoising of the one or more noise representations. Additionally, the one or more constraints on the one or more attributes of the character may comprise one or more of position, direction, angle, rotation, velocity, or contacts, and the one or more indicated motions are indicated by motions of another character. Furthermore, the one or more attributes conforming to the one or more constraints and are included in the one or more noise representations as in-painted ground truth data. In some embodiments, the systems, services, and/or circuitry is further configured by software to translate code to use the one or more attributes conforming to the one or more constraints in a subset of noise representations used to generate the frames of video, and is to include the representations of one or more attributes in the one or more noise representations based, at least in part, on random selection of the one or more attributes from a plurality of attributes. Further, the one or more neural networks are trained based, at least in part, on sets of video each comprising a plurality of character types performing the same type of motion, and/or perform any of the operations described above or elsewhere herein.

Global functions, device functions, host functions, and host/device functionsmay be mixed in CUDA source code. Each of global functionsmay be executable on a device and callable from a host. One or more of global functionsmay therefore act as entry points to a device. Each of global functionscan be a kernel. In a technique known as dynamic parallelism, one or more of global functionscan define a kernel that is executable on a device and callable from such a device. A kernel can be executed N (where N is any positive integer) times in parallel by N different threads on a device during execution.

2614 2616 2616 Each of device functionscan be executed on a device and callable from such a device only. Each of host functionscan be executed on a host and callable from such a host only. Each of host/device functionsmay define both a host version of a function that is executable on a host and callable from such a host only and a device version of the function that is executable on a device and callable from such a device only.

2610 2602 2602 2610 2602 2602 CUDA source codemay also include any number of calls to any number of functions that may be defined via a CUDA runtime API. CUDA runtime APImay include any number of functions that execute on a host to allocate and deallocate device memory, transfer data between host memory and device memory, manage systems with multiple devices, etc. CUDA source codemay also include any number of calls to any number of functions that may be specified in any number of other CUDA APIs. A CUDA API may be any API that is designed for use by CUDA code. CUDA APIs can include CUDA runtime API, a CUDA driver API, APIs for any number of CUDA libraries, etc., including any API(s) described elsewhere herein. Relative to CUDA runtime API, a CUDA driver API can be a lower-level API but can provide finer-grained control of a device. Examples of CUDA libraries include cuBLAS, cuFFT, cuRAND, cuDNN, etc.

2650 2610 2670 1 2684 2650 2670 1 2690 2690 CUDA compilermay compile input CUDA code (e.g., CUDA source code) to generate host executable code() and CUDA device executable code. CUDA compilermay be, but is not limited to, NVCC. Host executable code() can be a compiled version of host code included in input source code that is executable on CPU.

2620 2610 2630 2630 2612 2612 CUDA to HIP translation toolcan be configured to translate CUDA source codeto functionally similar HIP source code. HIP source codemay include a collection of human-readable code in a HIP programming language. HIP code can include human-readable code in a HIP programming language. A HIP programming language can include an extension of the C++ programming language that includes functionally similar versions of CUDA mechanisms to define device code and distinguish between device code and host code. A HIP programming language may include a subset of functionality of a CUDA programming language. For example, a HIP programming language includes mechanism(s) to define global functions, but such a HIP programming language may lack support for dynamic parallelism and therefore global functionsdefined in HIP code may be callable from a host only.

2630 2612 2614 2616 2618 2630 2632 2632 2602 2630 2632 HIP source codemay include any number (including zero) of global functions, any number (including zero) of device functions, any number (including zero) of host functions, and any number (including zero) of host/device functions.

CUDA to HIP translation toolcan include a tool known as hipify-clang that, relative to hipify-perl, executes a more complex and more robust translation process that involves parsing CUDA code using clang (a compiler front-end) and then translating resulting symbols. Converting CUDA code to HIP code may include modifications (e.g., manual edits) in addition to those performed by CUDA to HIP translation tool.

2620 2610 26 FIG. An example kernel may be translated by CUDA-to-HIP translation toolof, in accordance with at least one embodiment. CUDA source codepartitions an overall problem that a given kernel is designed to solve into relatively coarse sub-problems that can independently be solved using thread blocks. Each thread block includes any number of threads. Each sub-problem can be partitioned into relatively fine pieces that can be solved cooperatively in parallel by threads within a thread block. Threads within a thread block can cooperate by sharing data through shared memory and by synchronizing execution to coordinate memory accesses.

2610 CUDA source codecan organize thread blocks associated with a given kernel into a one-dimensional, a two-dimensional, or a three-dimensional grid of thread blocks. Each thread block includes any number of threads, and a grid includes any number of thread blocks.

A kernel can be a function in device code that is defined using a “_global_” declaration specifier. The dimension of a grid that executes a kernel for a given kernel call and associated streams may be specified using a CUDA kernel launch syntax. CUDA kernel launch syntax is specified as “KernelName<<<GridSize, BlockSize, SharedMemorySize, Stream>>>(KernelArguments);”. An execution configuration syntax can include a “<<< . . . >>>” construct that is inserted between a kernel name (“KernelName”) and a parenthesized list of kernel arguments (“KernelArguments”). CUDA kernel launch syntax can include a CUDA launch function syntax instead of an execution configuration syntax.

“GridSize” can be of a type dim3 and specify the dimension and size of a grid. Type dim3 may be a CUDA-defined structure that includes unsigned integers x, y, and z. If z is not specified, then z may default to one. If y is not specified, then y may default to one. The number of thread blocks in a grid can be equal to the product of GridSize.x, GridSize.y, and GridSize.z. “BlockSize” can be of type dim3 and specify the dimension and size of each thread block. The number of threads per thread block may be equal to the product of BlockSize.x, BlockSize.y, and BlockSize.z. Each thread that executes a kernel may be given a unique thread ID that is accessible within the kernel through a built-in variable (e.g., “threadIdx”).

With respect to CUDA kernel launch syntax, “SharedMemorySize” may be an optional argument that may specify a number of bytes in a shared memory that is dynamically allocated per thread block for a given kernel call in addition to statically allocated memory. With respect to CUDA kernel launch syntax, SharedMemorySize may default to zero. With respect to CUDA kernel launch syntax, “Stream” may be an optional argument that specifies an associated stream and defaults to zero to specify a default stream. A stream may be a sequence of commands (possibly issued by different host threads) that execute in order. Different streams may execute commands out of order with respect to one another or concurrently.

2610 CUDA source codemay include a kernel definition for an example kernel “MatAdd” and a main function. Main function may be host code that executes on a host and includes a kernel call that causes kernel MatAdd to execute on a device. Kernel MatAdd can add two matrices A and B of size N×N, where Nis a positive integer, and store the result in a matrix C. Main function can define a threadsPerBlock variable as 16 by 16 and a numBlocks variable as N/16 by N/16. Main function can then specify kernel call “MatAdd<<<numBlocks, threadsPerBlock>>> (A, B, C);”. As per CUDA kernel launch syntax, kernel MatAdd can be executed using a grid of thread blocks having a dimension N/16 by N/16, where each thread block has a dimension of 16 by 16. Each thread block can include 256 threads, a grid can be created with enough blocks to have one thread per matrix element, and each thread in such a grid may execute kernel MatAdd to perform one pair-wise addition.

2610 2630 2620 2610 2610 While translating CUDA source codeto HIP source code, CUDA to HIP translation toolmay translate each kernel call in CUDA source codefrom CUDA kernel launch syntax to a HIP kernel launch syntax and may convert any number of other CUDA calls in source codeto any number of other functionally similar HIP calls. HIP kernel launch syntax can be specified as “hipLaunchKernelGGL (KernelName, GridSize, BlockSize, SharedMemory Size, Stream, KernelArguments);”. Each of KernelName, GridSize, BlockSize, ShareMemorySize, Stream, and KernelArguments can have the same meaning in HIP kernel launch syntax as in CUDA kernel launch syntax (described previously herein). Arguments SharedMemorySize and Stream can be required in HIP kernel launch syntax and can be optional in CUDA kernel launch syntax.

2630 2610 2630 2610 2630 2610 A portion of HIP source codecan be identical to a portion of CUDA source codedepicted except for a kernel call that causes kernel MatAdd to execute on a device. Kernel MatAdd may be defined in HIP source codewith the same “_global_” declaration specifier with which kernel MatAdd is defined in CUDA source code. A kernel call in HIP source codemay be “hipLaunchKernelGGL (MatAdd, numBlocks, threadsPerBlock, 0, 0, A, B, C);”, while a corresponding kernel call in CUDA source codeis “MatAdd<<<numBlocks, threadsPerBlock>>> (A, B, C);”.

Code can be translated in any direction. For example, CUDA can be translated to HIP, and CUDA can be translated to OpenCL.

Streaming microprocessors may be referred to as streaming multiprocessors (“SMs”), stream processors (“SPs”), stream processing units (“SPUs”), compute units (“CUs”), execution units (“EUs”), and/or slices, where a slice in this context can refer to a portion of processing resources in a processing unit (e.g., 16 cores, a ray tracing unit, a thread director or scheduler).

2708 2708 One or more of GPU(s)may be power-optimized for best performance in automotive and embedded use cases. For example, GPU(s)could be fabricated on Fin field-effect transistor (“FinFET”) circuitry. Each streaming microprocessor may incorporate a number of mixed-precision processing cores partitioned into multiple blocks. For example, 64 PF32 cores and 32 FP64 cores could be partitioned into four processing blocks. Each processing block could be allocated 16 FP32 cores, 8 FP64 cores, 16 INT32 cores, two mixed-precision NVIDIA Tensor cores for deep learning matrix arithmetic, a level zero (“L0”) instruction cache, a scheduler (e.g., warp scheduler) or sequencer, a dispatch unit, and/or a 64 KB register file.

2708 2708 GPU(s)may include any number of access counters that may keep track of frequency of access of GPU(s)to memory of other processors. Access counter(s) may help ensure that memory pages may be moved to physical memory of a processor that is accessing pages most frequently, thereby improving efficiency for memory ranges shared between processors.

2704 2712 2712 2706 2708 2706 2708 2712 One or more of SoC(s)may include any number of cache(s), including those described herein.

SoC(s)may include a hardware acceleration cluster that may include optimized hardware accelerators and/or large on-chip memory. Large on-chip memory (e.g., 4 MB of SRAM), may enable a hardware acceleration cluster to accelerate neural networks and other calculations. A hardware acceleration cluster may be used to complement GPU(s)and to off-load some of tasks of GPU(s)(e.g., to free up more cycles of GPU(s)for performing other tasks). Accelerator(s)could be used for targeted workloads (e.g., perception, convolutional neural networks (“CNNs”), recurrent neural networks (“RNNs”), etc.) that may be stable enough to be amenable to acceleration. A CNN may include a region-based or regional convolutional neural networks (“RCNNs”) and Fast RCNNs (e.g., as used for object detection) or other type of CNN.

DLA(s) may include one or more Tensor processing units (“TPUs”) that may be configured to provide an additional ten trillion operations per second for deep learning applications and inferencing, such as TPU(s) described herein, e.g., in. TPUs may be accelerators configured to, and optimized for, performing image processing functions (e.g., for CNNs, RCNNs, etc.). DLA(s) may further be optimized for a specific set of neural network types and floating point operations, as well as inferencing. Design of DLA(s) may provide more performance per millimeter than a typical general-purpose GPU, and typically vastly exceeds performance of a CPU. TPU(s) may perform several functions, including a single-instance convolution function, supporting, for example, INT8, INT16, and FP16 data types for both features and weights, as well as post-processor functions. DLA(s) may quickly and efficiently execute neural networks, especially CNNs, on processed or unprocessed data for any of a variety of functions, including, for example: a CNN for object identification and detection using data from camera sensors; a CNN for distance estimation using data from camera sensors; a CNN for emergency vehicle detection and identification and detection using data from microphones; a CNN for facial recognition and vehicle owner identification using data from camera sensors; and/or a CNN for security and/or safety related events.

2708 2708 2708 2714 DLA(s) may perform any function of GPU(s), and by using an inference accelerator, for example, a designer may target either DLA(s) or GPU(s)for any function. For example, a designer may focus processing of CNNs and floating point operations on DLA(s) and leave other functions to GPU(s)and/or accelerator(s).

2714 2738 Accelerator(s)may include programmable vision accelerator (“PVA”), which may alternatively be referred to herein as a computer vision accelerator. PVA may be designed and configured to accelerate computer vision algorithms for advanced driver assistance system (“ADAS”), autonomous driving, augmented reality (“AR”) applications, and/or virtual reality (“VR”) applications.

For example, each PVA may include, for example, any number of reduced instruction set computer (“RISC”) cores, direct memory access (“DMA”), and/or any number of vector processors.

RISC cores may interact with image sensors (e.g., image sensors of any cameras described herein), image signal processor(s), etc. Each RISC core may include any amount of memory. RISC cores may use any of a number of protocols, depending on embodiment. RISC cores may execute a real-time operating system (“RTOS”). RISC cores may be implemented using one or more integrated circuit devices, application specific integrated circuits (“ASICs”), and/or memory devices. For example, RISC cores could include an instruction cache and/or a tightly coupled RAM.

2706 DMA may enable components of PVA to access system memory independently of CPU(s). DMA may support any number of features used to provide optimization to a PVA including supporting multi-dimensional addressing and/or circular addressing. DMA may support up to six or more dimensions of addressing, which may include block width, block height, block depth, horizontal block stepping, vertical block stepping, and/or depth stepping.

Vector processors may be programmable processors that may be designed to efficiently and flexibly execute programming for computer vision algorithms and provide signal processing capabilities. A PVA may include a PVA core and two vector processing subsystem partitions. A PVA core may include a processor subsystem, DMA engine(s) (e.g., two DMA engines), and/or other peripherals. A vector processing subsystem may operate as a primary processing engine of a PVA, and may include a vector processing unit (“VPU”), an instruction cache, and/or vector memory (e.g., “VMEM”). VPU core may include a digital signal processor such as, but not limited to, a single instruction, multiple data (“SIMD”), very long instruction word (“VLIW”) digital signal processor. A combination of SIMD and VLIW may enhance throughput and speed.

Each of vector processors may include an instruction cache and may be coupled to dedicated memory. As a result, each of vector processors may be configured to execute independently of other vector processors. Vector processors that may be included in a particular PVA may be configured to employ data parallelism. For instance, plurality of vector processors included in a single PVA may execute a common computer vision algorithm, but on different regions of an image. Vector processors included in a particular PVA may simultaneously execute different computer vision algorithms, on one image, or even execute different algorithms on sequential images or portions of an image. Among other things, any number of PVAs may be included in hardware acceleration cluster and any number of vector processors may be included in each PVA. PVA may include additional error correcting code (“ECC”) memory, to enhance overall system safety.

2714 2714 Accelerator(s)may include a computer vision network on-chip and static random-access memory (“SRAM”), for providing a high-bandwidth, low latency SRAM for accelerator(s). On-chip memory may include at least 4 MB SRAM, including, for example, eight field-configurable memory blocks, that may be accessible by both a PVA and a DLA. Each pair of memory blocks may include an advanced peripheral bus (“APB”) interface, configuration circuitry, a controller, and a multiplexer. Any type of memory may be used. A PVA and a DLA may access memory via a backbone that provides a PVA and a DLA with high-speed access to memory. A backbone may include a computer vision network on-chip that interconnects a PVA and a DLA to memory (e.g., using APB).

A computer vision network on-chip may include an interface that determines, before transmission of any control signal/address/data, that both a PVA and a DLA provide ready and valid signals. An interface may provide for separate phases and separate channels for transmitting control signals/addresses/data, as well as burst-type communications for continuous data transfer. An interface may comply with International Organization for Standardization (“ISO”) 26262 or International Electrotechnical Commission (“IEC”) 61508 standards, although other standards and protocols may be used.

2704 One or more of SoC(s)may include a real-time ray-tracing hardware accelerator. Real-time ray-tracing hardware accelerator may be used to quickly and efficiently determine positions and extents of objects (e.g., within a world model), to generate real-time visualization simulations, for RADAR signal interpretation, for sound propagation synthesis and/or analysis, for simulation of SONAR systems, for general wave propagation simulation, for comparison to LIDAR data for purposes of localization and/or other functions, and/or for other uses.

2714 2700 Accelerator(s)can have a wide array of uses for autonomous driving. A PVA may be used for key processing stages in ADAS and autonomous vehicles. A PVA's capabilities may be a good match for algorithmic domains needing predictable processing, at low power and low latency. In other words, a PVA can perform well on semi-dense or dense regular computation, even on small data sets, which might require predictable run-times with low latency and low power. In vehicle, PVAs might be designed to run classic computer vision algorithms, as they can be efficient at object detection and operating on integer math. For example, a PVA is used to perform computer stereo vision. A semi-global matching-based algorithm may be used in some examples, although this is not intended to be limiting. Applications for Level 3-5 autonomous driving use motion estimation/stereo matching on-the-fly (e.g., structure from motion, pedestrian recognition, lane detection, etc.). A PVA may perform computer stereo vision functions on inputs from two monocular cameras. A PVA may be used to perform dense optical flow. For example, a PVA could process raw RADAR data (e.g., using a 4D Fast Fourier Transform) to provide processed RADAR data. A PVA is used for time of flight depth processing, by processing raw time of flight data to provide processed time of flight data, for example.

2766 2700 2764 2760 A DLA may be used to run any type of network to enhance control and driving safety, including, for example, a neural network that outputs a measure of confidence for each object detection. Confidence may be represented or interpreted as a probability, or as providing a relative “weight” of each detection compared to other detections. A confidence measure enables a system to make further decisions regarding which detections should be considered as true positive detections rather than false positive detections. A system may set a threshold value for confidence and consider only detections exceeding threshold value as true positive detections. When an automatic emergency braking (“AEB”) system is used, false positive detections can cause vehicle to automatically perform emergency braking, which is obviously undesirable. Highly confident detections may be considered as triggers for AEB. a DLA may run a neural network for regressing confidence value. A neural network may take as its input at least some subset of parameters, such as, but not limited to, bounding box dimensions, ground plane estimate obtained (e.g., from another subsystem), output from IMU sensor(s)that correlates with vehicleorientation, distance, 3D location estimates of object obtained from neural network and/or other sensors (e.g., LIDAR sensor(s)or RADAR sensor(s)), among others.

2704 2716 2716 2704 2708 2716 2716 One or more of SoC(s)may include data store(s)(e.g., memory). Data store(s)may be on-chip memory of SoC(s), which may store neural networks to be executed on GPU(s)and/or a DLA. Data store(s)may be large enough in capacity to store multiple instances of neural networks for redundancy and safety. Data store(s)may comprise L2 or L3 cache(s).

2704 2710 2710 2704 2704 2704 2704 2706 2708 2714 2704 2700 2700 One or more of SoC(s)may include any number of processor(s)(e.g., embedded processors). Processor(s)may include a boot and power management processor that may be a dedicated processor and subsystem to handle boot power and management functions and related security enforcement. A boot and power management processor may be a part of a boot sequence of SoC(s)and may provide runtime power management services. A boot power and management processor may provide clock and voltage programming, assistance in system low power state transitions, management of SoC(s)thermals and temperature sensors, and/or management of SoC(s)power states. Each temperature sensor may be implemented as a ring-oscillator whose output frequency is proportional to temperature, and SoC(s)may use ring-oscillators to detect temperatures of CPU(s), GPU(s), and/or accelerator(s). If temperatures may be determined to exceed a threshold, then a boot and power management processor may enter a temperature fault routine and put SoC(s)into a lower power state and/or put vehicleinto a chauffeur to safe stop mode (e.g., bring vehicleto a safe stop).

2710 Processor(s)may further include a set of embedded processors that may serve as an audio processing engine which may be an audio subsystem that enables full hardware support for multi-channel audio over multiple interfaces, and a broad and flexible range of audio I/O interfaces. An audio processing engine is a dedicated processor core with a digital signal processor with dedicated RAM.

2710 Processor(s)may further include an always-on processor engine that may provide necessary hardware features to support low power sensor management and wake use cases.

2710 2710 2710 Processor(s)may further include a safety cluster engine that may include a dedicated processor subsystem to handle safety management for automotive applications. A safety cluster engine may include two or more processor cores, a tightly coupled RAM, support peripherals (e.g., timers, an interrupt controller, etc.), and/or routing logic. In a safety mode, two or more cores may operate, in a lockstep mode and function as a single core with comparison logic to detect any differences between their operations. Processor(s)may further include a real-time camera engine that may include a dedicated processor subsystem for handling real-time camera management. Processor(s)may further include a high-dynamic range signal processor that may include an image signal processor that is a hardware engine that is part of a camera processing pipeline.

2710 2770 2774 2704 Processor(s)may include a video image compositor that may be a processing block (e.g., implemented on a microprocessor) that implements video post-processing functions needed by a video playback application to produce a final image for a player window. A video image compositor may perform lens distortion correction on wide-view camera(s), surround camera(s), and/or on in-cabin monitoring camera sensor(s). In-cabin monitoring camera sensor(s) may be preferably monitored by a neural network running on another instance of SoC, configured to identify in cabin events and respond accordingly. An in-cabin system may perform lip reading to activate cellular service and place a phone call, dictate emails, change a vehicle's destination, activate or change a vehicle's infotainment system and settings, or provide voice-activated web surfing. Certain functions may be available to a driver when a vehicle is operating in an autonomous mode and may be disabled otherwise.

A video image compositor may include enhanced temporal noise reduction for both spatial and temporal noise reduction. For example, where motion occurs in a video, noise reduction weights spatial information appropriately, decreasing weights of information provided by adjacent frames. Where an image or portion of an image does not include motion, temporal noise reduction performed by video image compositor may use information from a previous image to reduce noise in a current image.

2708 2708 2708 A video image compositor may also be configured to perform stereo rectification on input stereo lens frames. A video image compositor may further be used for user interface composition when an operating system desktop is in use, and GPU(s)may not be required to continuously render new surfaces. When GPU(s)are powered on and active doing 3D rendering, a video image compositor may be used to offload GPU(s)to improve performance and responsiveness.

2704 2704 One or more SoC of SoC(s)may further include a mobile industry processor interface (“MIPI”) camera serial interface for receiving video and input from cameras, a high-speed interface, and/or a video input block that may be used for a camera and related pixel input functions. One or more of SoC(s)may further include an input/output controller(s) that may be controlled by software and may be used for receiving I/O signals that may be uncommitted to a specific role.

2704 2704 2764 2760 2702 2700 2758 2704 2706 One or more SoC of SoC(s)may further include a broad range of peripheral interfaces to enable communication with peripherals, audio encoders/decoders (“codecs”), power management, and/or other devices. SoC(s)may be used to process data from cameras (e.g., connected over Gigabit Multimedia Serial Link and Ethernet channels), sensors (e.g., LIDAR sensor(s), RADAR sensor(s), etc. that may be connected over Ethernet channels), data from bus(e.g., speed of vehicle, steering wheel position, etc.), data from GNSS sensor(s)(e.g., connected over a Ethernet bus or a CAN bus), etc. One or more SoC of SoC(s)may further include dedicated high-performance mass storage controllers that may include their own DMA engines, and that may be used to free CPU(s)from routine data management tasks.

2704 2704 2714 2706 2708 2716 SoC(s)may be an end-to-end platform with a flexible architecture that spans automation Levels 3-5, thereby providing a comprehensive functional safety architecture that leverages and makes efficient use of computer vision and ADAS techniques for diversity and redundancy, and provides a platform for a flexible, reliable driving software stack, along with deep learning tools. SoC(s)may be faster, more reliable, and even more energy-efficient and space-efficient than conventional systems. For example, accelerator(s), when combined with CPU(s), GPU(s), and data store(s), may provide for a fast, efficient platform for Level 3-5 autonomous vehicles.

Computer vision algorithms may be executed on CPUs, which may be configured using a high-level programming language, such as, but not limited to, C, to execute a wide variety of processing algorithms across a wide variety of visual data. However, CPUs may be oftentimes unable to meet performance requirements of many computer vision applications, such as, but not limited to, those related to execution time and power consumption, for example. Many CPUs may be unable to execute complex object detection algorithms in real-time, which is used in in-vehicle ADAS applications and in practical Level 3-5 autonomous vehicles.

2720 Embodiments described herein allow for multiple neural networks to be performed simultaneously and/or sequentially, and for results to be combined together to enable Level 3-5 autonomous driving functionality. For example, a CNN executing on a DLA or a discrete GPU (e.g., GPU(s)) may include text and word recognition, allowing reading and understanding of traffic signs, including signs for which a neural network has not been specifically trained. A DLA may further include a neural network that is able to identify, interpret, and provide semantic understanding of a sign, and to pass that semantic understanding to path planning modules running on a CPU Complex.

2708 Multiple neural networks may be run simultaneously, as for Level 3, 4, or 5 driving. For example, a warning sign stating “Caution: flashing lights indicate icy conditions,” along with an electric light, may be independently or collectively interpreted by several neural networks. Such warning sign itself may be identified as a traffic sign by a first deployed neural network (e.g., a neural network that has been trained), text “flashing lights indicate icy conditions” may be interpreted by a second deployed neural network, which informs a vehicle's path planning software (preferably executing on a CPU Complex) that when flashing lights may be detected, icy conditions exist. A flashing light may be identified by operating a third deployed neural network over multiple frames, informing a vehicle's path-planning software of a presence (or an absence) of flashing lights. All three neural networks may run simultaneously, such as, but not limited to, within a DLA and/or on GPU(s).

2700 2704 A CNN for facial recognition and vehicle owner identification may use data from camera sensors to identify presence of an authorized driver and/or owner of vehicle. An always-on sensor processing engine may be used to unlock a vehicle when an owner approaches a driver door and turns on lights, and, in a security mode, to disable such vehicle when an owner leaves such vehicle. In this way, SoC(s)can provide for security against theft and/or carjacking.

2796 2704 2758 2762 A CNN for emergency vehicle detection and identification may use data from microphonesto detect and identify emergency vehicle sirens. SoC(s)use a CNN for classifying environmental and urban sounds, as well as classifying visual data. A CNN running on a DLA is trained to identify a relative closing speed of an emergency vehicle (e.g., by using a Doppler effect). A CNN may also be trained to identify emergency vehicles specific to a local area in which a vehicle is operating, as identified by GNSS sensor(s). When operating in Europe, a CNN may seek to detect European sirens, and when in North America, a CNN may seek to identify only North American sirens. Once an emergency vehicle is detected, a control program may be used to execute an emergency vehicle safety routine, slowing a vehicle, pulling over to a side of a road, parking a vehicle, and/or idling a vehicle, with assistance of ultrasonic sensor(s), until emergency vehicles pass.

Network interfacemay be used to enable wireless connectivity to Internet cloud services (e.g., with server(s) and/or other network devices), with other vehicles, and/or with computing devices (e.g., client devices of passengers). To communicate with other vehicles, a direct link may be established between vehicleand another vehicle and/or an indirect link may be established (e.g., across networks and over the Internet). Direct links may be provided using a vehicle-to-vehicle communication link. A vehicle-to-vehicle communication link may provide vehicleinformation about vehicles in proximity to vehicle(e.g., vehicles in front of, on a side of, and/or behind vehicle). Such aforementioned functionality may be part of a cooperative adaptive cruise control functionality of vehicle.

2724 2736 2724 Network interfacemay include an SoC that provides modulation and demodulation functionality and enables controller(s)to communicate over wireless networks. Network interfacemay include a radio frequency front-end for up-conversion from baseband to radio frequency, and down conversion from radio frequency to baseband.

Any number of GNSS sensor(s)may be used, including, for example, a GPS using a USB connector with an Ethernet-to-Serial (e.g., RS-232) bridge.

2700 2760 2760 2700 2760 2702 2760 2760 2760 Vehiclemay further include RADAR sensor(s). RADAR sensor(s)may be used by vehiclefor long-range vehicle detection, even in darkness and/or severe weather conditions. RADAR functional safety levels may be ASIL B. RADAR sensor(s)may use a CAN bus and/or bus(e.g., to transmit data generated by RADAR sensor(s)) for control and to access object tracking data, with access to Ethernet channels to access raw data in some examples. A wide variety of RADAR sensor types may be used. For example, RADAR sensor(s)may be suitable for front, rear, and side RADAR use. One or more sensor of RADAR sensors(s)is a Pulse Doppler RADAR sensor.

2760 2760 2738 2760 2700 2700 s RADAR sensor(s)may include different configurations, such as, but not limited to, long-range with narrow field of view, short-range with wide field of view, short-range side coverage, etc. Long-range RADAR may be used for adaptive cruise control functionality. Long-range RADAR systems may provide a broad field of view realized by two or more independent scans, such as, but not limited to, within a 250 m (meter) range. RADAR sensor(s)may help in distinguishing between static and moving objects and may be used by ADAS systemfor emergency brake assist and forward collision warning. Sensors() included in a long-range RADAR system may include monostatic multimodal RADAR with multiple (e.g., six or more) fixed RADAR antennae and a high-speed CAN and FlexRay interface. With six antennae, a central four antennae may create a focused beam pattern, designed to record vehicle'ssurroundings at higher speeds with minimal interference from traffic in adjacent lanes. Another two antennae may expand field of view, making it possible to quickly detect vehicles entering or leaving a lane of vehicle.

2760 2738 Mid-range RADAR systems may include, as an example, a range of up to 160 m (front) or 80 m (rear), and a field of view of up to 42 degrees (front) or 150 degrees (rear). Short-range RADAR systems may include any number of RADAR sensor(s)designed to be installed at both ends of a rear bumper. When installed at both ends of a rear bumper, a RADAR sensor system may create two beams that constantly monitor blind spots in a rear direction and next to a vehicle. Short-range RADAR systems may be used in ADAS systemfor blind spot detection and/or lane change assist.

2700 2762 2762 2700 2762 2762 2762 Vehiclemay further include ultrasonic sensor(s). Ultrasonic sensor(s), which may be positioned at a front, a back, and/or side location of vehicle, may be used for parking assist and/or to create and update an occupancy grid. A wide variety of ultrasonic sensor(s)may be used, and different ultrasonic sensor(s)may be used for different ranges of detection (e.g., 2.5 m, 4 m). Ultrasonic sensor(s)may operate at functional safety levels of ASIL B.

2700 2764 2764 2764 2700 2764 Vehiclemay include LIDAR sensor(s). LIDAR sensor(s)may be used for object and pedestrian detection, emergency braking, collision avoidance, and/or other functions. LIDAR sensor(s)may operate at functional safety level ASIL B. Vehiclemay include multiple LIDAR sensors(e.g., two, four, six, etc.) that may use an Ethernet channel (e.g., to provide data to a Gigabit Ethernet switch).

2764 2764 2764 2700 2764 2764 LIDAR sensor(s)may be capable of providing a list of objects and their distances for a 360-degree field of view. Commercially available LIDAR sensor(s)may have an advertised range of approximately 100 m, with an accuracy of 2 cm to 3 cm, and with support for a 100 Mbps Ethernet connection, for example. One or more non-protruding LIDAR sensors may be used. LIDAR sensor(s)may include a small device that may be embedded into a front, a rear, a side, and/or a corner location of vehicle. LIDAR sensor(s), in such an embodiment, may provide up to a 120-degree horizontal and 35-degree vertical field-of-view, with a 200 m range even for low-reflectivity objects. Front-mounted LIDAR sensor(s)may be configured for a horizontal field of view between 45 degrees and 135 degrees.

2700 2700 2700 LIDAR technologies, such as, but not limited to, 3D flash LIDAR, may also be used. 3D flash LIDAR uses a flash of a laser as a transmission source, to illuminate surroundings of vehicleup to approximately 200 m. A flash LIDAR unit may include a receptor, which records laser pulse transit time and reflected light on each pixel, which in turn corresponds to a range from vehicleto objects. Flash LIDAR may allow for highly accurate and distortion-free images of surroundings to be generated with every laser flash. Four flash LIDAR sensors may be deployed, one at each side of vehicle. 3D flash LIDAR systems include a solid-state 3D staring array LIDAR camera with no moving parts other than a fan (e.g., a non-scanning LIDAR device). Flash LIDAR device may use a 5 nanosecond class I (eye-safe) laser pulse per frame and may capture reflected laser light as a 3D range point cloud and co-registered intensity data.

2700 2766 2766 2700 2766 2766 2766 Vehiclemay further include IMU sensor(s). IMU sensor(s)may be located at a center of a rear axle of vehicle. IMU sensor(s)may include, for example, accelerometer(s), magnetometer(s), gyroscope(s), a magnetic compass, magnetic compasses, and/or other sensor types. In six-axis applications, but not limited to, IMU sensor(s)may include accelerometers and gyroscopes. In nine-axis applications, but not limited to, IMU sensor(s)may include accelerometers, gyroscopes, and magnetometers.

2766 2766 2700 2766 2766 2758 IMU sensor(s)may be implemented as a miniature, high performance GPS-Aided Inertial Navigation System (“GPS/INS”) that combines micro-electro-mechanical systems (“MEMS”) inertial sensors, a high-sensitivity GPS receiver, and advanced Kalman filtering algorithms to provide estimates of position, velocity, and attitude. IMU sensor(s)may enable vehicleto estimate its heading without requiring input from a magnetic sensor by directly observing and correlating changes in velocity from a GPS to IMU sensor(s). IMU sensor(s)and GNSS sensor(s)may be combined in a single integrated unit.

2700 2796 2700 2796 Vehiclemay include microphone(s)placed in and/or around vehicle. Microphone(s)may be used for emergency vehicle detection and identification, among other things.

2700 2768 2770 2772 2774 2798 2776 2700 2700 2700 2700 Vehiclemay further include any number of camera types, including stereo camera(s), wide-view camera(s), infrared camera(s), surround camera(s), long-range camera(s), mid-range camera(s), and/or other camera types. Cameras may be used to capture image data around an entire periphery of vehicle. Types of cameras used may depend on vehicle. Any combination of camera types may be used to provide necessary coverage around vehicle. A number of cameras deployed may differ depending on embodiment. For example, vehiclecould include six cameras, seven cameras, ten cameras, twelve cameras, or another number of cameras. Cameras may support, as an example, Gigabit Multimedia Serial Link (“GMSL”) and/or Gigabit Ethernet communications. Each camera might be as described with more detail previously herein.

2700 2742 2742 2700 2742 Vehiclemay further include vibration sensor(s). Vibration sensor(s)may measure vibrations of components of vehicle, such as, but not limited to, axle(s). For example, changes in vibrations may indicate a change in road surfaces. When two or more vibration sensorsmay be used, differences between vibrations may be used to determine friction or slippage of road surface (e.g., when a difference in vibration is between a power-driven axle and a freely rotating axle).

2700 2738 2738 2738 Vehiclemay include ADAS system. ADAS systemmay include an SoC, in some examples. ADAS systemmay include any number and combination of an autonomous/adaptive/automatic cruise control (“ACC”) system, a cooperative adaptive cruise control (“CACC”) system, a forward crash warning (“FCW”) system, an automatic emergency braking (“AEB”) system, a lane departure warning (“LDW”) system, a lane keep assist (“LKA”) system, a blind spot warning (“BSW”) system, a rear cross-traffic warning (“RCTW”) system, a collision warning (“CW”) system, a lane centering (“LC”) system, and/or other systems, features, and/or functionality.

2760 2764 2700 2700 2700 ACC system may use RADAR sensor(s), LIDAR sensor(s), and/or any number of camera(s). ACC system may include a longitudinal ACC system and/or a lateral ACC system. A longitudinal ACC system monitors and controls distance to another vehicle immediately ahead of vehicleand automatically adjusts speed of vehicleto maintain a safe distance from vehicles ahead. A lateral ACC system performs distance keeping and advises vehicleto change lanes when necessary. A lateral ACC is related to other ADAS applications, such as, but not limited to, LC and CW.

2724 2726 2700 2700 A CACC system uses information from other vehicles that may be received via network interfaceand/or wireless antenna(s)from other vehicles via a wireless link, or indirectly, over a network connection (e.g., over the Internet). Direct links may be provided by a vehicle-to-vehicle (“V2V”) communication link, while indirect links may be provided by an infrastructure-to-vehicle (“I2V”) communication link. In general, V2V communication provides information about immediately preceding vehicles (e.g., vehicles immediately ahead of and in same lane as vehicle), while I2V communication provides information about traffic further ahead. A CACC system may include either or both I2V and V2V information sources. Given information of vehicles ahead of vehicle, a CACC system may be more reliable and it has potential to improve traffic flow smoothness and reduce congestion on road.

2760 An FCW system is designed to alert a driver to a hazard, so that such driver may take corrective action. An FCW system uses a front-facing camera and/or RADAR sensor(s), coupled to a dedicated processor, DSP, FPGA, and/or ASIC, that is electrically coupled to provide driver feedback, such as, but not limited to, a display, speaker, and/or vibrating component. An FCW system may provide a warning, such as, but not limited to, in form of a sound, visual warning, vibration and/or a quick brake pulse.

2760 An AEB system detects an impending forward collision with another vehicle or other object and may automatically apply brakes if a driver does not take corrective action within a specified time or distance parameter. AEB system may use front-facing camera(s) and/or RADAR sensor(s), coupled to a dedicated processor, DSP, FPGA, and/or ASIC. When an AEB system detects a hazard, it will typically first alert a driver to take corrective action to avoid collision and, if that driver does not take corrective action, that AEB system may automatically apply brakes in an effort to prevent, or at least mitigate, an impact of a predicted collision. An AEB system may include techniques such as, but not limited to, dynamic brake support and/or crash imminent braking.

2700 2700 2700 An LDW system provides visual, audible, and/or tactile warnings, such as, but not limited to, steering wheel or seat vibrations, to alert driver when vehiclecrosses lane markings. An LDW system does not activate when a driver indicates an intentional lane departure, such as, but not limited to, by activating a turn signal. An LDW system may use front-side facing cameras, coupled to a dedicated processor, DSP, FPGA, and/or ASIC, that is electrically coupled to provide driver feedback, such as, but not limited to, a display, speaker, and/or vibrating component. An LKA system is a variation of an LDW system. An LKA system provides steering input or braking to correct vehicleif vehiclestarts to exit its lane.

2760 A BSW system detects and warns a driver of vehicles in an automobile's blind spot. A BSW system may provide a visual, audible, and/or tactile alert to indicate that merging or changing lanes is unsafe. A BSW system may provide an additional warning when a driver uses a turn signal. A BSW system may use rear-side facing camera(s) and/or RADAR sensor(s), coupled to a dedicated processor, DSP, FPGA, and/or ASIC, that is electrically coupled to driver feedback, such as, but not limited to, a display, speaker, and/or vibrating component.

2700 2760 An RCTW system may provide visual, audible, and/or tactile notification when an object is detected outside a rear-camera range when vehicleis backing up. An RCTW system includes an AEB system to ensure that vehicle brakes may be applied to avoid a crash. An RCTW system may use one or more rear-facing RADAR sensor(s), coupled to a dedicated processor, DSP, FPGA, and/or ASIC, that is electrically coupled to provide driver feedback, such as, but not limited to, a display, speaker, and/or vibrating component.

2700 2736 2738 2738 Conventional ADAS systems may be prone to false positive results which may be annoying and distracting to a driver, but typically may not be catastrophic, because conventional ADAS systems alert a driver and allow that driver to decide whether a safety condition truly exists and act accordingly. Vehicleitself decides, in case of conflicting results, whether to heed result from a primary computer or a secondary computer (e.g., a first controller or a second controller of controllers). For example, ADAS systemmay be a backup and/or secondary computer for providing perception information to a backup computer rationality module. A backup computer rationality monitor may run redundant diverse software on hardware components to detect faults in perception and dynamic driving tasks. Outputs from ADAS systemmay be provided to a supervisory MCU. If outputs from a primary computer and outputs from a secondary computer conflict, a supervisory MCU can determine how to reconcile conflict to ensure safe operation.

A primary computer may be configured to provide a supervisory MCU with a confidence score, indicating that primary computer's confidence in a chosen result. If that confidence score exceeds a threshold, that supervisory MCU may follow that primary computer's direction, regardless of whether that secondary computer provides a conflicting or inconsistent result. Where a confidence score does not meet a threshold, and where primary and secondary computers indicate different results (e.g., a conflict), a supervisory MCU may arbitrate between computers to determine an appropriate outcome.

2704 A supervisory MCU may be configured to run a neural network(s) that is trained and configured to determine, based at least in part on outputs from a primary computer and outputs from a secondary computer, conditions under which that secondary computer provides false alarms. Neural network(s) in a supervisory MCU may learn when a secondary computer's output may be trusted, and when it cannot. For example, when that secondary computer is a RADAR-based FCW system, a neural network(s) in that supervisory MCU may learn when an FCW system is identifying metallic objects that may not be, in fact, hazards, such as, but not limited to, a drainage grate or manhole cover that triggers an alarm. When a secondary computer is a camera-based LDW system, a neural network in a supervisory MCU may learn to override LDW when bicyclists or pedestrians may be present and a lane departure is, in fact, a safest maneuver. A supervisory MCU may include at least one of a DLA or a GPU suitable for running neural network(s) with associated memory. A supervisory MCU may comprise and/or be included as a component of SoC(s).

2738 ADAS systemmay include a secondary computer that performs ADAS functionality using traditional rules of computer vision, and that secondary computer may use classic computer vision rules (if-then), and presence of a neural network(s) in a supervisory MCU may improve reliability, safety and performance. For example, diverse implementation and intentional non-identity makes an overall system more fault-tolerant, especially to faults caused by software (or software-hardware interface) functionality. For example, if there is a software bug or error in software running on a primary computer, and non-identical software code running on a secondary computer provides a consistent overall result, then a supervisory MCU may have greater confidence that an overall result is correct, and a bug in software or hardware on that primary computer is not causing a material error.

2738 2738 An output of ADAS systemmay be fed into a primary computer's perception block and/or a primary computer's dynamic driving task block. For example, if ADAS systemindicates a forward crash warning due to an object immediately ahead, a perception block may use this information when identifying objects. A secondary computer may have its own neural network that is trained and thus reduces a risk of false positives, as described herein.

2700 2730 2730 2730 2700 2730 2734 2730 2700 2738 Vehiclemay further include infotainment SoC(e.g., an in-vehicle infotainment system (IVI)). Although illustrated and described as an SoC, infotainment system SoC, may not be an SoC, and may include two or more discrete components. Infotainment SoCmay include a combination of hardware and software that may be used to provide audio (e.g., music, a personal digital assistant, navigational instructions, news, radio, etc.), video (e.g., TV, movies, streaming, etc.), phone (e.g., hands-free calling), network connectivity (e.g., LTE, WiFi, etc.), and/or information services (e.g., navigation systems, rear-parking assistance, a radio data system, vehicle related information such as, but not limited to, fuel level, total distance covered, brake fuel level, oil level, door open/close, air filter information, etc.) to vehicle. For example, infotainment SoCcould include radios, disk players, navigation systems, video players, USB and Bluetooth connectivity, carputers, in-car entertainment, WiFi, steering wheel audio controls, hands free voice control, a heads-up display (“HUD”), HMI display, a telematics device, a control panel (e.g., for controlling and/or interacting with various components, features, and/or systems), and/or other components. Infotainment SoCmay further be used to provide information (e.g., visual and/or audible) to user(s) of vehicle, such as, but not limited to, information from ADAS system, autonomous driving information such as, but not limited to, planned vehicle maneuvers, trajectories, surrounding environment information (e.g., intersection information, vehicle information, road information, etc.), and/or other information.

2730 2730 2702 2700 2730 2736 2700 2730 2700 Infotainment SoCmay include any amount and type of GPU functionality. Infotainment SoCmay communicate over buswith other devices, systems, and/or components of vehicle. Infotainment SoCmay be coupled to a supervisory MCU such that a GPU of an infotainment system may perform some self-driving functions in event that primary controller(s)(e.g., primary and/or backup computers of vehicle) fail. Infotainment SoCmay put vehicleinto a chauffeur to safe stop mode, as described herein.

2700 2732 2732 2732 2730 2732 2732 2730 Vehiclemay further include instrument cluster(e.g., a digital dash, an electronic instrument cluster, a digital instrument panel, etc.). Instrument clustermay include a controller and/or supercomputer (e.g., a discrete controller or supercomputer). Instrument clustermay include any number and combination of a set of instrumentation such as, but not limited to, a speedometer, fuel level, oil pressure, tachometer, odometer, turn indicators, gearshift position indicator, seat belt warning light(s), parking-brake warning light(s), engine-malfunction light(s), supplemental restraint system (e.g., airbag) information, lighting controls, safety system controls, navigation information, etc. Information may be displayed and/or shared among infotainment SoCand instrument cluster. Instrument clustermay be included as part of infotainment SoC, or vice versa.

2700 System may include server(s), network(s), and any number and type of vehicles, including vehicle. Server(s) may include a plurality of GPUs, PCIe switches, and/or CPUs. GPUs, CPUs, and PCIe switches may be interconnected with high-speed interconnects such as, but not limited to, for example, NVLink interfaces developed by NVIDIA and/or PCIe connections. GPUs can be connected via any interconnects, such as NVLink and/or NVSwitch SoC, and GPUs and PCIe switches can be, for example, connected via PCIe interconnects. Each of server(s) may include any number of GPUs, CPUs, and/or PCIe switches, in any combination. For example, server(s) could each include eight, sixteen, thirty-two, and/or more GPUs.

Server(s) may receive, over network(s) and from vehicles, image data representative of images showing unexpected or changed road conditions, such as, but not limited to, recently commenced roadwork. Server(s) may transmit, over network(s) and to vehicles, neural networks, updated or otherwise, and/or map information, including information regarding traffic and road conditions. Updates to map information may include updates for HD map, such as, but not limited to, information regarding construction sites, potholes, detours, flooding, and/or other obstructions. Neural networks, and/or map information may have resulted from new training and/or experiences represented in data received from any number of vehicles in an environment, and/or based at least in part on training performed at a data center (e.g., using server(s) and/or other servers).

Server(s) may be used to train machine learning models (e.g., neural networks) based at least in part on training data. Training data may be generated by vehicles, and/or may be generated in a simulation (e.g., using a game engine). Any amount of training data can be tagged (e.g., where associated neural network benefits from supervised learning) and/or undergoes other pre-processing. Any amount of training data may not be tagged and/or pre-processed (e.g., where associated neural network does not require supervised learning). Once machine learning models are trained, machine learning models may be used by vehicles (e.g., transmitted to vehicles over network(s)), and/or machine learning models may be used by server(s) to remotely monitor vehicles.

Server(s) may receive data from vehicles and apply data to up-to-date real-time neural networks for real-time intelligent inferencing. Server(s) may include deep-learning supercomputers and/or dedicated AI computers powered by GPU(s), such as, but not limited to, a DGX and DGX Station machines developed by NVIDIA. Alternatively, server(s) may include deep learning infrastructure that uses CPU-powered data centers.

2700 2700 2700 2700 2700 2700 Deep-learning infrastructure of server(s) may be capable of fast, real-time inferencing, and may use that capability to evaluate and verify health of processors, software, and/or associated hardware in vehicle. For example, deep-learning infrastructure may receive periodic updates from vehicle, such as, but not limited to, a sequence of images and/or objects that vehiclehas located in that sequence of images (e.g., via computer vision and/or other machine learning object classification techniques). Deep-learning infrastructure may run its own neural network to identify objects and compare them with objects identified by vehicleand, if results do not match and deep-learning infrastructure concludes that AI in vehicleis malfunctioning, then server(s) may transmit a signal to vehicle instructing a fail-safe computer of vehicleto assume control, notify passengers, and complete a safe parking maneuver.

Server(s) may include GPU(s) and one or more programmable inference accelerators (e.g., NVIDIA's TensorRT 3 devices). A combination of GPU-powered servers and inference acceleration may make real-time responsiveness possible. Where performance is less critical, servers powered by CPUs, FPGAs, and other processors may be used for inferencing.

Cloud computing can include a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over technology infrastructure, which can be referred to as “in the cloud,” that supports them. Cloud computing may incorporate infrastructure as a service, platform as a service, software as a service, and other variations that have a common theme of reliance on the Internet for satisfying computing needs of users. A typical cloud deployment, such as in a private cloud (e.g., enterprise network), or a data center (DC) in a public cloud (e.g., Internet) can include thousands of servers (or alternatively, VMs), hundreds of Ethernet, Fiber Channel or Fiber Channel over Ethernet (FCOE) ports, switching and storage infrastructure, etc. A cloud can also include network services infrastructure like IPsec VPN hubs, firewalls, load balancers, wide area network (WAN) optimizers etc. Remote subscribers can access cloud applications and services securely by connecting via a VPN tunnel, such as an IPsec VPN tunnel.

Cloud computing may include a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Cloud computing may be characterized by on-demand self-service, in which a consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human inter-action with each service's provider. Cloud computing may be characterized by broad network access, in which capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). Cloud computing may be characterized by resource pooling, in which a provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically as-signed and reassigned according to consumer demand. In at least one embodiment, there is a sense of location independence in that a customer generally has no control or knowledge over an exact location of provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines. Cloud computing may be characterized by rapid elasticity, in which capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. In at least one embodiment, to a consumer, capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. Cloud computing may be characterized by measured service, in which cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to a type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both a provider and consumer of a utilized service.

Cloud computing may be associated with various services. Cloud Software as a Service (SaaS) may refer to as service in which a capability provided to a consumer is to use a provider's applications running on a cloud infrastructure. Applications can be accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). In at least one embodiment, consumer does not manage or control underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with a possible exception of limited user-specific application configuration settings.

Cloud Platform as a Service (PaaS) may refer to a service in which a capability provided to consumer is to deploy onto cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by a provider. In at least one embodiment, a consumer does not manage or control underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over deployed applications and possibly application hosting environment configurations.

Cloud Infrastructure as a Service (IaaS) may refer to a service in which a capability provided to a consumer is to provision processing, storage, networks, and other fundamental computing resources where a consumer is able to deploy and run arbitrary software, which can include operating systems and applications. In at least one embodiment, consumer does not manage or control underlying cloud infrastructure, but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Cloud computing may be deployed in various ways. A private cloud may refer to a cloud infrastructure that is operated solely for an organization. A private cloud may be managed by an organization or a third party and may exist on-premises or off-premises. A community cloud may refer to a cloud infrastructure that is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). A community cloud may be managed by organizations or a third party and may exist on-premises or off-premises. A public cloud may refer to a cloud infrastructure that is made available to a general public or a large industry group and is owned by an organization providing cloud services.

At least one embodiment of the disclosure can be described in view of the following clauses:

As will be apparent to one of ordinary skill in the art, other variations are within spirit of present disclosure. Thus, while disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in drawings and have been described above in detail. It should be understood, however, that there is no intention to limit disclosure to specific form or forms disclosed, but on contrary, intention is to cover all modifications, alternative constructions, and equivalents falling within spirit and scope of disclosure, as defined in appended claims.

11 23 FIGS.- 16 As described further herein, processors, such as those disclosed incan use instructions to perform any of the operations described herein. Instructions, for example, can be performed using one or more threads. A thread block can include any number of threads of execution. A workgroup can be a thread block. A processor can execute a group of threads (e.g.,threads). A group of threads can also be referred to as a warp, or subgroup, or wavefront (e.g., as used by AMD and Intel). Each thread in a warp, wave, subgroup, or wavefront can belong to a single thread block and can be configured to process a different set of data based on a single set of instructions. A lane can be a thread. A work item can be a thread, such as, but not limited to, e.g., with OpenCL.

11 23 FIGS.- A processor, such as, processors described further herein (e.g.,) can include one or more threads that can perform instructions synchronously. A thread can perform instructions synchronously. For example, a thread can perform a sequence of two instructions. An output of the first instruction can be input to the second instruction.

11 23 FIGS.- In at least one embodiment, a thread performs an instruction asynchronously if the thread performs one or more subsequent instructions before a processor's completion of all operations corresponding to the instruction have been completely been performed. For example, the thread can perform the instruction to cause a processor to queue or otherwise begin performing an operation and the thread can perform subsequent instructions before the processor has completed performing the operation. A processor, such as, processors described further herein (e.g.,) can perform instructions asynchronously. For example, a thread may submit or issue an instruction to be performed by processor, and processor can perform the instruction independently of a thread that can be performing other instruction(s). A thread may submit or issue an instruction that can be performed by processor, and, for example, can inform one or more threads (the same thread or other threads) when the processor has performed a previously submitted or issued instruction. A thread may perform a first instruction to wait to be informed that processor has performed previously submitted or issued instructions, and, for example, output from the processor can be available to the thread. Output from processor can be input to a thread performing a second instruction. Instructions can be performed asynchronously in a variety of sequences. For example, one or more threads may submit one or more instructions to a processor, and processor may perform instructions in a sequence that is the same or different than an order submitted by the threads. Processor may specify a sequencing for the instructions that the processor performs.

Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. Use of “may” and/or “can” is intended to indicate by way of example without limiting any particular embodiment or component or other function described above, below, or elsewhere herein. “Connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. Use of term “set” (e.g., “a set of items”) or “subset” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal.

Conjunctive language, such as, but not limited to, phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). Number of items in a plurality can be at least two, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.”

Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. A process such as, but not limited to, those processes described herein (or variations and/or combinations thereof) can be performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. Code can be stored on a computer-readable storage medium, for example, in form of a computer program comprising a plurality of instructions executable by one or more processors. A computer-readable storage medium can be a non-transitory computer-readable storage medium that excludes transitory signals (e.g., a propagating transient electric or electromagnetic transmission) but includes non-transitory data storage circuitry (e.g., buffers, cache, and queues) within transceivers of transitory signals. Code (e.g., executable code or source code) can be stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. A set of non-transitory computer-readable storage media can include multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. Executable instructions can be executed such that different instructions are executed by different processors—for example, a non-transitory computer-readable storage medium store instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. Different components of a computer system can have separate processors and different processors execute different subsets of instructions.

An arithmetic logic unit can include a set of combinational logic circuitry that takes one or more inputs to produce a result. An arithmetic logic unit can be used by a processor to implement mathematical operation such as, but not limited to, addition, subtraction, or multiplication. An arithmetic logic unit is used to implement logical operations such as, but not limited to, logical AND/OR or XOR. An arithmetic logic unit can be stateless, and made from physical switching components such as, but not limited to, semiconductor transistors arranged to form logical gates. An arithmetic logic unit may operate internally as a stateful logic circuit with an associated clock. An arithmetic logic unit may be constructed as an asynchronous logic circuit with an internal state not maintained in an associated register set. An arithmetic logic unit can be used by a processor to combine operands stored in one or more registers of the processor and produce an output that can be stored by the processor in another register or a memory location.

As a result of processing an instruction retrieved by the processor, the processor may present one or more inputs or operands to an arithmetic logic unit, causing the arithmetic logic unit to produce a result based at least in part on an instruction code provided to inputs of the arithmetic logic unit. The instruction codes provided by the processor to the ALU may be based at least in part on the instruction executed by the processor. Combinational logic in the ALU may process the inputs and produces an output which is placed on a bus within the processor. A processor can select a destination register, memory location, output device, or output storage location on the output bus so that clocking the processor causes the results produced by the ALU to be sent to the desired location.

In the scope of this application, the term arithmetic logic unit, or ALU, is used to refer to any computational logic circuit that processes operands to produce a result. For example, in the present document, the term ALU can refer to a floating point unit, a DSP, a tensor core, a shader core, a coprocessor, or a CPU.

One or more components of systems and/or processors disclosed above can communicate with one or more CPUs, ASICs, GPUs, FPGAs, or other hardware, circuitry, or integrated circuit components that include, e.g., an upscaler or upsampler to upscale an image, an image blender or image blender component to blend, mix, or add images together, a sampler to sample an image (e.g., as part of a DSP), a neural network circuit that is configured to perform an upscaler to upscale an image (e.g., from a low resolution image to a high resolution image), or other hardware to modify or generate an image, frame, or video to adjust its resolution, size, or pixels; one or more components of systems and/or processors disclosed above can use components described in this disclosure to perform methods, operations, or instructions that generate or modify an image.

Computer systems can be configured to implement one or more services that singly or collectively perform operations of processes described herein and such computer systems are configured with applicable hardware and/or software that enable performance of operations. Further, a computer system that implements at least one embodiment of present disclosure is a single device and, in another embodiment, is a distributed computer system comprising multiple devices that operate differently such that distributed computer system performs operations described herein and such that a single device does not perform all operations.

Use of any and all examples, or example language (e.g., “such as, but not limited to,”) provided herein, is intended merely to better illuminate embodiments of disclosure and does not pose a limitation on scope of disclosure unless otherwise claimed. No language in specification should be construed as indicating any non-claimed element as essential to practice of disclosure.

All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.

In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as, but not limited to, “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as, but not limited to, electronic, quantities within computing system's registers and/or memories into other data similarly represented as physical quantities within computing system's memories, registers or other such information storage, transmission or display devices.

In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as, but not limited to, tasks, threads, and intelligent agents. Also, each process may refer to multiple processes, for carrying out instructions in sequence or in parallel, continuously or intermittently. Terms “system” and “method” are used herein interchangeably insofar as system may embody one or more methods and methods may be considered a system.

References may be made to obtaining, acquiring, receiving, or inputting analog or digital data into a subsystem, computer system, or computer-implemented machine. Processes of obtaining, acquiring, receiving, or inputting analog and digital data can be accomplished in a variety of ways such as, but not limited to, by receiving data as a parameter of a function call or a call to an application programming interface. Processes of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. Processes of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, processes of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism.

Although descriptions herein set forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities may be defined above for purposes of description, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.

Furthermore, although subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that subject matter claimed in appended claims is not necessarily limited to specific features or acts described. Rather, specific features and acts are disclosed as example forms of implementing the claims.
